Don't think so. I suppose than Morrison choose to make the story away from earth-0 main characters to don't mix with the other characters continuities. Better that way. The ongoing series must start then with the recruitment of a character from earth-0. (Yes, I want a ongoing series after Convergence. Yes I know than it would be not made by Morrison, but dreaming is free. I want an ongoing after all this is finished). And on "Jane Garrick", (who have a earth-0 & earth-2 Flash mash-up suit) could be Speed-Freak, from earth-47.
On a sidenote, is interesting than Superdemon is featured in the last chapter and maybe have a higher relevance in the story. Interesting, Superdemon, Super-God. I didn't saw a connection.
