Advice for carry options

So, I like magazine compatibility. I travel a bunch and would love to just have two handguns on me (one is a nightstand gun for home/bedside in the trailer) and the other is a ccw. I have an MR920 and a g17 and love how they can share magazines, but I really don’t like the Glock platform. It’s fine, but others are way better. I typically carry a p365xl daily, as the mr920 prints too much for my job (I work in a legal, but non-permissive environment surrounded by anti-gunners). I also have a Canik tp9 elite combat that is amazing to run.

I’m getting rid of the mr920 and probably the g17. Should I get the p365x macro for my more “substantial” hd gun and just carry the xl, or should I get the Canik elite sc and have a Canik combo? The sig is literally twice the price, and I don’t think I will shoot it as well as the larger Canik.

Also, I want to make this as even a trade as possible…

Is this a ridiculous premise/idea?
