I'd be surprised if they did much one-stop routing without significant O&D on both legs. With props it's not much faster than connecting at a hub and G4 is doing 4 weekly nonstop XNA-SFB this summer. I can't imagine there would be much demand for a BKG-HSV or TUL-SHV/LIT flight so it would be dependent on connections.
Looking at the HSV-MCO schedule, it appears that it is an HSV RON, but there would be time for the ATR to fly to another airport and RON there, so I guess BKG-HSV-MCO isn't totally implausible. Will be interesting to see what gets announced in the coming weeks.
Huntsville is the type of demographic that Branson Tourism appeals to.
BKG is just outside of the supposed full load range to MCO. That's why I suggested that and it's pretty much a perfect flight pattern. If they are going to fly out of MSY, MEM seems like low hanging fruit for a roomy turboprop with the 46 seat configuration instead of the 48 or 50 ones.
I could easily see a try at BKG/MEM/MSY. MEM would be the primary driver for each leg with some possible pull power for BKG to MSY from NWA and Springfield.
