Yes.
It would be a breath of fresh air to step into the shoes of some characters within the Dragon Age universe who aren't responsible for the fate of the world.
It would be a great platform to tell small stories that don't necessarily impact the state of the world, but add depth.
Short vignettes about some little people, small players in the world, with smaller scale conflicts like say:
A pirate on Isabela's ship who discovers a plot of mutiny and must choose sides.
A servant in Orlais playing the Game.
A prisoner of the Qunari who must choose whether or not to accept the Qun.
A bartender in Kirkwall who gets tangled up in a gang-related territory dispute.
A dwarf of the smith caste who was tasked with crafting something for a noble that was secretly cursed and becomes a fugitive looking to clear your name.
A mage tempted by a demon.
That said, I don't think Bioware needs Telltale for this at all. They could just use the same engine and assets they already have, just adding a timer to certain dialogue options, and locking the camera angle. I think if they had a splinter team using the assets within the game already, they could do this easily (easy when compared to DAI proper). All they would need are writers who are interested in telling smaller, in-depth stories.
Personally, I'm totally on board.
