There are more games in the season to be played for baseball, basketball and hockey. There's fewer for the footballs but to be environmentally friendly, there are a lot of places with a lot of seats already in existence for MLS and NFL games to be played. Sure, they might not meet contemporary luxury box standards of this pinnacle leagues, but the thoughts are much more environmentally friendly. Hell, I'd love to have an Ohio MLS team like "Ohio Divided" splitting time between football stadiums in Cleveland and Cincinnati.
But anyway, here are a few examples for such possibilities of sharing.
Place of Play Expansion (Tag Team (Co-Location)), Name Expansion (and regional exhibition), possibly as a rebrand. An example of this would be the NBA's Clippers and what woulda' or shoulda' or coulda' happened with them under new ownership. Just change the name to the West Coast Clippers. Consider playing in Las Vegas and Seattle from time to time. Same thing with NHL's Coyotes.
The idea of league expansion could occur as an expansion team or relocation/co-location of an existing team.
Names like Nashville, Memphis, and New Orleans. Maybe what? The year 2040? But what if the Marlins relocated part-time to Tampa and the Rays become the Southland Rays of Nashville and Charlotte?
That's what would be left after what I'd do now. Maybe. Some of these towns even aren't on the fence right now.
Further down the road, whatta' we got?
Little Rock, Omaha, San Antonio. Stuff like that. Like Oklahoma City.
It's years and years and decades for the likes of Albuquerque or Boise.

Can you see some of the pictures I'm painting here?
I see this sharing way as the difference for getting a team or more in 20 to 40 years as opposed to a hundred years away for the likes of SLC, OKC, Albuquerque, Austin, Boise, Louisville, Birmingham, Omaha and Virginia Beach. Proximity is an issue. Close but not too close is the business way for the shared (but regional) identity with two or more places to play for one team, like Rangers baseball being in San Antonio and Dallas metro and the Marlins being in Miami as well as Tampa. That's not to say I haven't schemed up international ideas of sharing for the likes of Tampa/Monterrey and Las Vegas/Montreal.
