You'd think that sci-fi fans wouldn't limit their imaginations so much. I think this is a fantastic idea and I hope we see more Star Trek crossovers in the future. Farscape would be pretty cool.
I think Farscape
would work a lot better.
Another one that's just occurred to me -- Doctor Who
and Edgar Rice Burroughs' Barsoom. Dynamite and IDW teaming up on that could be pretty cool, especially if we got an Alex Ross cover.
