Not sure DC will see a market for another GA omnibus, but I wouldn't hate it.
I just looked at DCU Guide and there are 5-6 non-GA chronological appearances of Oliver Queen in that time range (and the Zero issue). I'd bet 81-90 get orphaned or maybe get a tpb only, then they'd do all of 0, 91-137, 1,000,000 as a single Connor Hawke omni or series of fat tpbs.
