I haven't tried to do anything with cherry's. I only own one cherry board mx, the scorpius m10, and haven't really been adventurous enough to tear it apart since I sort of like it the way it is. The key is if the switches are secure enough in just a mounting plate, with the terminals exposed.
The plates for these two came from model f type boards like the dc-2014, and zenith. Both older xt boards, which I cut down to size, and got cheap off ebay, under $40, and used the switches from as well. The original top one is all blue alps, which I was always really happy with. The new one is complicated whites. Both feel really great to type on, so I'm really happy with both of them.
Basically both of these are made up from parts from 2 or 3 different donor boards with the hhkb lite chips driving them with rewired matrix's.
If the cherry switches can be mounted to a plate solidly, with exposed terminals, there's no reason why you shouldn't be able to copy an existing matrix with wires just like I've done here. Ripster and a few others gave me the idea, specifically the redo of the matrix's with his n52 hack, as well as lessons on how matrix's work. He might be able to help you more, since his n52 hack was also cherries. I know he had a lot of trouble mounting them perfectly because he didn't have a plate.
If you do go for it the important part to remember is to number all the lead wires and switches really well, cause it can become quite a mess and confusing. I usually have a couple misswires or faults since it's hundreds of solder points, and easy to mess up 1 or two, that I have to go back and trace with a multimeter. This time I found a tiny short cause by stray solder between wire 14 and 15 underneath the board that was causing double keypresses of like o and p anytime either the o or p key was pressed. It was a total pain to track down.
