The idea: 3d-print very basic 5/5.2mm height, 15mm square enclosures for each switch to hold the switch top firmly, instead of a plate, just solder these individually plated switches
The cause/reasoning: To make it simpler to switch between costar/cherry stabs (Costar stabs as a larger/complete 1u plate that includes the switch and stab cutouts) - mainly to make the PCB-mount cherry stabs more accessible + laziness / the need to experiment
Worries:
1) The bottom-down sounds could be bad, with 5mm plates they are just so deeply awesome
2) I'm not sure whether some switches would become crooked after a while
3) Removing keycaps could warp the PCB/individual switch
Pros:
1) Very practical for a custom keyboard, getting a plate done is challenging, the stabilisers also rarely play along
2) (compared to a regular pcb-mount setup) The switches won't get torned open during keycap removal
Making these tiny plates 5.2mm would make them contact the pcb, making them 5/4.8mm would let the switch touch the PCB, I guess 4.8mm is more risk-free, as there won't be height discrepancies
I have 0 experience with PCB-mount keyboard, I would appreciate some insight/advice
