Rogue War, good as it is, was very obviously two story arcs shoved together at the end. Johns also left a bunch of loose plot lines all over the place which, admittedly, is typical him but the big one is the three visits. His run was ended and the comic was gone 5 issues later as it buffered with fill ins into Infinite Crisis, its scheduled, synergized cancellation point.
I'm just saying the timeline is not very good for the point you're trying to make. It's well known that IC was supposed to springboard a Barry return and that's in the works a year into Didio's tenure.
