I'd say go for it -- I've never been sure on the logistics of shared accounts like that on any site, but they seem to work, and what the hell, more exposure is always a good thing, right?
Sounds like a great idea. :3 Make a journal or something if you do end up making one so I can follow.

It's definitely not a bad idea in the very least. If anything it would make it easier to actually see the end result of the collabs themselves than in either one of your galleries.
Just to the point that someone wanting a collab may confuse one of your own pieces as a collab one and vice versa, all that jazz.
That and it gives me something else to watch here on Weasyl. :3 <3
