Dec 4, 2015 at 19:04 comment added Jason Starr This is also one of the issues in trying to construct a Quot scheme for sheaves with non-proper support, so perhaps there is a more direct connection between those two problems. Also, perhaps you could prove that there is a filtering colimit of algebraic spaces such that the colimit Yoneda functor represents the functor of flatification (in the category of proper, birational morphisms).
