Plate mounted? That will be quite a hassle to desolder.
plate's a massive bonus, a hassle but worth it. The thing about this item isn't the switches or the springs, the plate and board are really well made.
If someone wants the switches I'll have the board and plate

I've got two still to convert but, ghetto red this and put a teensy in there. Cheap and well made bit of kit. Cut the plate and board to tkl and put some wires in to the controller and you've a great keyboard. Lot of work mind.
