What if you were alicent…
imagine for a second you were alicent and yes, you married king viserys I and produce the green siblings, what marriage alliances would you push for the green siblings ( my personal hot take is that alicent was very, very against the incest thing because she was from Oldtowne, where they literally had a campaign over the incest thing— sure, the doctrine came into being but it must have not been that long since it happened in Jaehaerys and Alysanne’s time and also pure Valyrian Targaryens marrying are a different thing and your own kids marrying each other be a whole different situation )
or if you do think it would be best for aegon and helaena to be wed and have their twins and maelor, what alliances would you push for ?
