I will assume Indy will get a team after Portland and Charlotte do, whenever that is.
Just keeping it simple like that (not thinking Mexico or Montreal), I'll imagine out west'ish, at the time of Indianapolis expansion, will be Oklahoma City or Las Vegas.

We could have jerseys as the Indy East Coast Clowns and part-time a series or two or ten in Puerto Rico. It could be a two place team. That's how it started out: the Cincinnati-Indianapolis Clowns. Then it stayed in the League as one of the last of the league, barnstorming like the Harlem Globetrotters of basketball fame.
Enough of Indy being a toss-up for Cards, Cubs or Reds Country. Be a rivalry to these neighbors, not amidst them.
This could be a post all on its own:
