MM2 main board swap

[Minipilot14]

Is it possible to swap the main board of a mm1 with a mm2 to shoot in 4k since the camera is capable of doing so?

Very doubtful, aside from anything else it's a micro USB vs USB-C port and there's a connector on the Min 2 board to drive the front LED, those are just the 'external' physical differences I have noticed.
Then you have the electronic pairing of the camera and boards to probably rework plus any pairing with the other board.
Perhaps different radio circuits too, due to differing communication protocols, and those are just the things I can think of.
Sorry.
