Now consider the set of actions B which are possible for an omnibenevolent God to do. Clearly B is a subset of A. To show this, consider action b in B. if b is allowed under omnibenevolence, there must be a contradictory action ~b which is not. For instance, if letting a child die is in B, (for whatever obscure reason God has for this) letting the child live must not be in B. Thus the set of actions an omnibenevolent god cannot do, C = A - B, is not empty. Since omnipotence implies being able to do all of A, an omnibenevolent god is not omnipotent. Forget about saying god chooses to not do actions in C. It is not a matter of choice - he cannot do them, since doing so would cause him to violate omnibenevolence. In fact, we can posit another entity, not omnibenevolent, who could do all actions in A - this entity would be more powerful than God, which is a contradiction on God’s nature. .

You have a set of things, “C” which God could do but will not do. To do them would violate his nature. I don’t disagree.
Yes, you can posit a different being, who’s omnipotent but not omnibenevolent - a chaotic neutral god for example. Positing him does not make him more powerful than God, just makes him different. Besides, from a Christian point of view, there is no being that is greater than God, that fits your proposed omnipotent but not omnibenevolent entity, so your posited god is an empty set.
Your argument is valid, though. There are things that God could do but does not do because his nature simply excludes those choices. Your argument seems to be that since God will not do something that is against his nature, he’s in fact not omnipotent. If he’s not omnipotent, then he cannot be God.
Am I summarizing correctly?
Perhaps then you’ve uncovered a flaw in the way we present things, in the standard theological “shorthand” that Christians use to present theology.
I’d argue that it’s possible to do more, even as a human, that we’d ever actually do. We, too, are limited by our natures.
I could point a gun at you and threaten to kill you. Could I kill you? Yes. I have the ability, instrument, and necessary index finger to pull the trigger. Would I kill you? No. If you’re no threat to me and my family, you don’t deserve death. My morality, my nature, removes that choice.
Could God do anything? Yes. Would God do anything? No. He cannot violate his nature.
I think you’ve won a point concerning concerning the standard Christian shorthand used to discuss theology. I don’t think you’ve successfully attacked belief in God at all.
Most free-will believing Christians also talk about omniscience rather too easily without delving deeply in what it means to mix free-will and God’s ability to know the future. There’s at least three schools of thought on this that I know right now and chapters and chapters are of many books are dedicated to exploring this subject, too.
Saying “Omniscience” is shorthand, just as “Omnipotence” is. Pointing out that “this word does not mean what you think it means” is, frankly, obvious. But tossing around words like this are standard Christian shorthands for more complicated subjects.
You haven’t won a point here in anything other than, perhaps, grammar or semantics. I’ll concede that in theology “omnipotence” and “omniscience” are more complicated ideas that simply “all powerful” or “all knowing”.
Next you might take on the phrase “born again” with the deep insights that a birth canal is not, in fact, involved.
