I'm not sure about GYY/Gary, Indiana working as the airport for Chicago. I think that I passed two tollbooth plazas from that airport area to downtown/Chicago region. It's after those toll booths, that one feels that they have entered Chicago and a metropolitan area. No El or cab access to the Loop.
Atleast with ILG it's pretty much toll free to most of Philly/SE PA, and TTN is toll free for Philly and many parts of NJ catchment.
Also, since Chicago is a destination- it'd be a wet blanket essentially flying TTN-GYY instead of MDW without the amenities of the L line or cabs to downtown.
FTW maybe a good airport since it can be a focus that's one for the South essentially, and likely if F9 is going to do more tertiary airports, it'd fly from tertiary to a primary airport. FTW-DEN, FTW-MDW, FTW-ATL, FTW-LAS, FTW-MCO. If F9 can find the right plane for TTN-DEN, it'd probably start TTN-Texas also.

That maybe a dealbreaker. I mean if it can only fly to DTW or CLE, it's probably not worth the investment.
