Not really, no. But Seb has sworn that he'd abdicate before he'd allow me to be put aside, but the Chantry doesn't want that either since it would lead to absolute chaos in Starkhaven. Everyone and their third cousin vying for the throne.

And the Chantry's feathers were already ruffled plenty by the ~~Herald of Andraste~~ being a mage from Ostwick. They'll just have to deal with Seb marrying me.
