Definitely! Bridge Tief, why not! Need a new scout, how bout her? She seems to know what's what, and must be up to something out there right!

I think a mini quest written in text, combined with a bark or two could make pretty much anyone a winner. Then after a few months playing around with the concept, perhaps Larian can see who everyone picked or if any ideas they didn't think of before suddenly present themselves. This info could be used to inform their decisions about what makes an interesting potential companion in addition to just the Origins.
