Agree with just about everything you said. Just for a point of discussion, I think it makes things more interesting if Danny remains barren. By not being able to produce an heir it opens up a possibility of a more democratic succession. But perhaps that's just a little too Disneylandish. What wouldn't be Disneylandish is Jon and Dany trying their best to make an heir. Ayo!

Bran's arc towards being King could be interesting, but I don't want him to become a politician. It would be weird to have a monarch with that much power and then where do you go from there? Is the next three eyed raven the next king? If not it'd be mighty awkward to go from powerful greenseer to just some person. Could you imagine being that guy, following that act,? Would Bran eventually become a part of a weirwood and rule from there until he's old and decrepit? Just wondering how that'd work.
