That's not ideal (US didn't like being a PHX-PHL/CLT dumbbell either).
They could end up large enough at that point to perhaps attempt a mid-con hub, although I have no idea where. The largest middle-USA (which I'll define as west of Appalachians and east of the Rockies) airports that aren't currently a hub for another airline (I'll ignore anything WN focus city briefly), by passenger counts, are STL, HOU, BNA, AUS, and MCI. None of those are really obvious, and VX/B6 currently have little presence in them (none at all in STL or MCI, and BNA is only starting in May for B6). STL is well located and has the infrastructure built more than most, but would be a tough go with how much WN has increased at STL.
