The beginning may be replaceable rather than a core part but I might as well go into it.That seems like it would be a massive blunder on his part. Telling Madoka about it seems like it would vastly decrease, rather than increase, her willingness to contract, much as the witchbomb did. Knowing that each repetition is exacerbating the problem only gives her more reason to try to avoid making more loops necessary. Or worse, to do what she did at the end of the series and try to use her wish to simultaneously end the loops and deny Kyubey his payday.
The potentialbomb is really only an effective weapon if used against Homura, because she equates potential with suffering and it gives her cause to blame herself for everything. Against anyone else, it just doesn't have the same emotional impact. If Kyubey instead told Madoka, he would just be throwing away his shot... or worse, shooting himself in the foot.
I don't think it's unreasonable to conclude that the vagueness of her wish (as compared to the specificity of her wish to become Madokami) indicates that she probably knew much less about the situation than she did in canon.
That said, other aspects of your theory do have merit. We know that a Madowish can retcon history, so it's not outside the realm of possibility that the changes we're seeing in the PMAS timeline were created by her wish. It might be worth trying to see if there are any discrepancies between Homura's knowledge of past timelines and this one that predate anything we could have effected since our arrival.
(That's also one of the more unique uses of the Literary Agent Hypothesis that I've ever seen. )
We may not see whatever action was taken, but we see the result. By all indication, Kyuubey very much got something out of that wish: He got another potential magical girl with ludicrous power. Even without something like Sabrina appearing, a time resetting wish from Madoka would increase the potential of the people close to her.
As far as rules lawyeryness goes, for all that it's concise, I'm of the impression that Madoka's wish is pretty well handled. She doesn't wish for an outcome, she wishes for a possibility. And that makes a certain amount of sense: Magic is a double sided thing. Ask for something good and you'll get it, but there's going to be something bad to go with it. Ask for a possibility or a chance on the other hand, and it may well be that you lay the foundation for a possible wonderful outcome in exchange for a possible horrible one. (In the same manner, ask for a means to fix everything, and you may solve everything with it, or you may break everything with it.)
(Maybe this Sabrina will live forever but fail to save the people she cares for. Maybe she'll just blow up Mitakihara... and leave any other problems that emerged in the wish with no one to resolve them. Or maybe she'll make herself into the new cog in the system that changes everything.)
