Well I'd like for it to keep on trucking like COIE never happened.

Then add some of the later Infinitors and children of ASS/JSA (Rich, Jesse, Beth, etc). Maybe have some of the older JSAers retire so some Infinitors can move up like they wanted and Infinity Inc doesn't get too bloated. Then some of the more modern JSAers (Jakeem, Stargirl, Cyclone, Sand, etc). Then maybe eventually that Justice Society Infinity idea, but that would be way later.

I'd really prefer it not get totally bloated by Superman and Batman characters like New 52 Earth 2 did immediately after Robinson left. Peeg and Huntress should be enough for a long while. I could stomach maybe having Earth 2 Dick and Val Zod, but that's it.
