Ron, you will need to opt for the .25 barrel breech slide turned to the same diameter as the .22 which is no trouble at all. plenty of material to allow for that.
I’m sure once you get used to the dis/reassembly then it will indeed be a five min job.
I swap barrels often and my POI never changes somehow.
It takes me about 5 mins to do. I swap between 24inched .22 cal to 18inched .177 barrels. Taking about the power wheel and other internals is simple. Taking it apart has taught me a lot. It’s quite a simple air gun.
