Yeah, but the Queen Consort can romace him. Unlike Anora, were your trapped in a loveless marriage. And I betcha, the Queen Consort is most likely more influencing then the lowly Prince Consort who is actively known as prince Consort. The Queen Consort isn't known as the Princess Consort though, only as the Queen Consort. I suppose the one is known as the Prince Consort (and Anora doesn't even take on your name, either. But neither does the Queen Consort for Alistair does either.) Does not have as much power as the Queen Consort, who is known without the Consort part of her name. However, he is know as the Prince Consort, not only a King or Prince (without the Consort tittle of his name).
Romance Alistair in order to become queen is not mandatory,while Anora can't be romanced,and actually this is a good thing "at least for me" since "romance" are somehow locked especially in the keep,mean that you have to chose one,having for example Anora as wife and Leliana/Morrigan as lover isn't so bad,or in DAO there was the chance for the Prince consort to marry Anora while having both romcances with Leliana and Morrigan activated,albeit the keep allow to only set for one for Inquisition since honestly have all three (it is possible without using chat in DAO just by paying attention carefully to Leliana and Morrigan critical moments of their romances) was exaggerated .
They are interchangeable titles who mean the same thing,how can be a Queen consort be more influential of a Princess consort if the title means the same thing and it can be used with the same weight
Her husband is also Cailan half brother , Alistair is not a complete noble like Cailan but he still remain a more powerful candidate than Anora and a stronger "Match" for the Queen Cousland consort .
The other marriage between Anora and a male Cousland is completely different Queen Anora is less legitimated than the male Cousland
,not only only becuase of her birthright but also because of what her father and her administration did during the blight
She has her problems in keeping the nobility quite while keep looking for the Prince/King consort in order to resolve the situation,since the nobles of Ferelden are pressuring her with their whole "give me an heir ,queen Anora,It's since the kingdom of Cailan that we demanded this",this is somehow in her codex.
No one of this is present with AListair since the nobles are content enough albeit there is no heir too,they still have a Theirin for the moment who didn't had Loghain as a father to ruin the reputation.
At least this is my thought,if you put someone like AListair on the throne you are pretty much equal in power to him,since he is not the HoF and he does not possess all the lands of her wife (Gwaren,Amaranthine, partnership with Fergus,friendship with Bhelen ecc..) but he is still Maric son and an heir of Calenhad,even if i personally don care this seem still important for people like Eamon and te conservativism.
Anora on the other hand has an husband that she accepted to marry in order to take the throne while not having Maric as a father but Loghain, who lost his reputation,and his husband has all those lands and riches and titles and is also a noble.
For my personal canon i also preferred to have a grey warden and only one to the throne not two of them.
