+ 3 pain using one scope. I thought through the logistics, and decided no way.
All my rifles have Picatinny / MIL-STD-1913 rails; not for continuous optic swap, but ease of changing scopes if the need arises.
Suggestion: Before you liquidate all your optics, pick one you like the best. Set it up for swapping, and try this for a few months. If you can tolerate it, go for it. If not, the most you are out is possibly the cost of a mount.
BTW, I use typical Badger rings and a quality torque wrench. When I have removed and re-installed optics, there has been no issue with zero. *If* I were to go to one scope (which I will not), the mounting system would not change from the present setup.
Good Luck
