Code Orange also did an elevator on a turret in 2019. The bearing system for this turret was a thing of beauty.
As the other posts above have said, this is a non-trivial exercise and should not be attempted with a lazy susan style turntable. I would also not recommend this unless you have good machining capabilities and are able to manufacture a substantial structure similar to these examples. Also, it is pretty late in the build season to be starting a large design and manufacturing project like this. It would need to provide a pretty substantial benefit to your game strategy in order to undertake that level of risk, IMO.
