Dracen, probably not. Dracen was a character created by, and for, a Kickstarter backer. So we don't really have rights to do anything more with him than was done with him in Changeling.
However, one day we'd really love to do a game about all of Corvin's brothers - not just Merle, but Aiah, Lonan, Raaf, Ransley, and Bran as well. OwO I think it would be fun to explore the six of them and what their work is really like in their weird, little cafe.
