I'd be interested in such a collection. Kickstarter really has more disadvantages than advantages, I think, for a collection, unless one already has significant name recognition - and then there is the thing where Kickstarter reward levels can be time- and resource-intensive.

(Revision is almost always a good idea.)

Standard practice with collections seems to suggest there should be at least one previously unpublished story... In terms of publicising, it would probably be good to try to get a guest post with Aiden Moher or the Book Smugglers?

...I'm being helpy, aren't I? Sorry.
