Go with the 2 stall engine idea!
A turntable is often used at the end of the line to turn a locomotive, certain passenger cars, snowplows and other equipment that has a "front end" if there is no room to install a retrun loop or wye.
When I visited the Strausburg RR in PA a few years ago, they had purchased a turntable to install at the end of their line to turn the locomotive so it would not have to run backwards on the return trip. I do not know if they have installed it or not.

I have a 90' Walthers turntable and matching 3 stall Cornerstone roundhouse. The TT is installed and running and the roundhouse has been built but not yet installed. Now that it is time to wire the whisker tracks and glue down the house, I find I am having second thoughts about using it at all. It is flimsy, plastic, and much larger than my small RR needs.
Besides turning steamers, for what else could the TT be used? A 2 stall engine house comes to mind. I have the FSM kit just waiting to be built.
