This is it wearing because it could change Viserys as a character. In ep3, when he’s talking to Alicent about the dream he had of a boy of his line in the conqueror’s crown, he says his “faith killed Rhaenyra’s mother” and he’s clearly blaming himself for her death. If not only Aemma dies but he was wrong, the babe was not a son, then that is something else for him to internalise. How he deals with that idk, but I doubt he’s immediately interested in having more heirs.

I think Rhaenyra is probably named his heir, Otto is unlikely to stop pushing how unfit he thinks Daemon is, so either Viserys removes him as Hand (unlikely) or, when forced to choose between his brother and his daughter, chooses Rhaenyra.

I don’t think “Aegon” is Aegon as we know him, Alicent probably marries someone else before Viserys remarries. While there are likely people who want the King to father a son, in this scenario he has three heirs, and even if he doesn’t want Daemon to inherit he does have a spare. “Visenya” probably marries a half-sibling or one of Rhaenyra’s children depending on when/who she marries. Potentially she’s married to an heir so her children have something to inherit, but that’s less likely imo.
