I can make a case but it is something that I alone am probably interested in.
Thanks for you help I really appreciate it.

Personally, I would never assume I am the only person in the world that worries about this and that.. So this aspect of gravity was addressed before, I am sure (but I can not tell you by whom and when at the moment..).
However, when you are in some problem more deeply (by this I mean understanding the math involved) , then you will know if something is relevant or not.
And in case of binary systems, the time is not important in the way you are trying to imply... Yes, the gravity propagates by the speed of light, but this propagation time is so short compared to other time frames that you can comfortably put those effects aside as the first approximation.. possibly even as the second and the third:-) .
