I've heard of that edit, yeah. I've long been curious to see it, particularly the IM2/Hulk/Thor crosscut, but I decided it wasn't how I wanted to approach this particular rewatch. We don't get much information on how those three films interact chronologically, and there's some conflicting evidence (if they're all supposed to be taking place within the same week, the Hulk's rampage in Virginia being on TV while Fury is talking to Tony at the end of IM2 seems a bit off -- shouldn't it have been the breakage of Harlem instead?), but it would be fun to see how it all fits together.
