I looked at the boxes again, good news a side of the box is removable so no need to cut into the drywall. The side of the box clips into place, it's hard to remove and replace but it's doable!
Also looked at the switches, have one 4 way switch and the other two are 3 ways. No idea how they are wired into the lights though.
