Combining Two Ender 3 Printers

Hello! I have two Ender 3 printers that I'm just not using as much since I got a Bambu Lab A1. Since it's always a good idea to have more than one printer, I still want to keep one around, but I wondered what I could do if I combined them both together and am looking for suggestions. I have an Ender 3 Pro and an Ender 3 V2, both have a BL touch. The V2 has a glass bed, the Pro has the magnetic flexi-sheet. I have some Raspberry Pi's of varying vintage lying around so klipper maybe? No real mods done.

Thoughts?
