Now, if the object mass that the shadow falls on is doubled without changing its area presented to the shadow, will there be any increase in the shadowing effect? Can changing the mass of the shadowed object cause more CGs to hit it from the rear than what is represented by the shadow?

Let's say that the shadow represents a shortfall of 42 CGs on the "windward" side of the object it falls on. Now if we double the objects mass that the shadow is falling on, that same shadow must now represent a shortfall of 84 CGs on the now doubled object. How could this be so?

So, we're not talking about actual quantities per second of actual CGs as real entities? I am beginning to see your point of view but it still seems inconsistent with your other statements.
Perhaps this will clarify the issue I have.
______________________
There is a hoola hoop in space some distance from a planet. It's in a plane perpendicular to a vertical line to the center of the planet. Is it your position that ...
" a finite number of CGs (X) normally go through the hoola hoop from each direction ... but ... from the planet side which casts a shadow ... that number is less (X-N). Therefore, the excess CGs coming through the side away from the planet is then just 'N'. If we double the planet mass this excess is increased to '2N' "
If so, we have exactly 'N' CGs available to push whatever is the size of the hoola hoop at that same distance. So, we put a mass there and record its acceleration. Then we double this mass (keeping it at exactly the same volume as the original) and get 1/2 the acceleration since we have the same quantity of propellant ('N') pushing a double mass. Now, double the planet mass too ... the acceleration produced must now again be equal to that of the first mass since we now have twice the propellant ('2N' CGs). The "forces" on these bodies must then be
<center>
F = 1M x 1A (on the single mass single planet)
F = 1M x (1/2)A (on the double mass single planet)
F = 2M x 1A (on the duble mass double planet)
</center>
[Please remember that I am here talking about CGs as a "physical propellant" (a pusher) as you suggest they are. I realize that a doubled mass single planet should produce the same acceleration as the single mass, single planet ... but ... by the stated theory of "pushing", it simply cannot do so unless modified by some sort of miraculous multiplying effect. You say that the CGs have a 'propelling' effect which I take to be analogous to momentum transfer as is the case with other types of mechanical interactions. Hence, they are logically equivalent to ... and should match the properties of ... other mechanical propellants. If there are 'N' propellants they cannot do the same job on two masses as they can on one mass. This would make no physical sense. I see 'N' as a fixed, real number of particles per unit time ... however large they may be ... so that once they hit and rebound, they have done their job and can provide no more accelerations. By saying that each particle feels the shortfall (rather than the aggregate body), you are in effect increasing that 'N' shortfall to greater than 'N' per unit time without increasing the source body's mass which is the cause of the 'N' shortfall. I am saying that if you double the object mass, each particle in that mass will "feel" only 1/2 the excess CGs that they previously felt because 'N' is a finite number distributed over twice as many object particles.]
Now, we go back to the single mass single planet and move the object mass to 1/2 the distance. It's excess CG count must then increase fourfold by the inverse square law.
<center>F = 1M x 4A (on on a single mass 1/2 the distance)</center>
Thus, the inconsistency ...
<font size="4">2M x 1A</font id="size4"> (on the double mass, double planet)
<font size="4">does not =</font id="size4">
<font size="4">1M x 4A </font id="size4">(on a single mass, single planet, 1/2 the distance)
which is a required equality by Newton's gravitational equation.

I didn't mean to talk of "hoola hoops" ;o) I meant to speak of the flux through an area per unit time. The hoola hoop just delimits an area. Anyway, what I have trouble understanding is ... a finite number of CGs in a finite time (N/t) comes through a finite volume containing a finite number of MIs (M). So that we have ...
<center><font size="4">N/tM </font id="size4">= CGs per unit time per MI </center>
Then we double the mass (in the same volume) and have 2M. Now we have ...
<center><font size="4"> N/t2M </font id="size4">= CGs per unit time per MI </center>
Yet your answer implies that ...
<center><font size="4">N/tM =N/t2M </font id="size4"> </center>
which does not make sense mathematically or physically unless you are implying that MIs feel the excess flux of CGs as a percentage rather than as a constant number N.
Hmmmm ... wait a minute ...
Is this what you mean ... ?
The excess flux is a real number like "523" ... then you put one mass in the way and it gets hit by "36" of the 523. Then you put another mass there as well (doubling) and it absorbs another "36" of the remaining (523-36=)"487" ...?
The light dawns ... I concede the point.
Everything is AOK as long as the CGs are incredibly abundant which is necessarily the case with MM (even in the Standard Model the number of gravitons must number in the "gazillions" per unit time per unit volume). Then, the only problem with the inverse square law is its algebraic inconsistency about which we can agree to disagree, i.e.
