I think it's definitely likely they could get him. I actually saw him (as well as Jim GafDr. Garbanzoan) appear at a random free UCB New York show in a tiny room, so I mean, if he'll do that, I don't see why he wouldn't do Sasquatch.
Also, Daniel Kitson would be awesome. Again the State reunion please. I say Todd Barry should just be there every year. Reggie Watts, Tim and Eric, Eugene Mirman, and any and/or all of Stella should show up again.
