I'm not clear on what your situation is - I have the Rogue
VB-100 and the switch plate is already pearloid, matching the pickguard.
However - if your replacement needs a copper sheet underneath it, just buy some thin copper sheet material at a craft store and cut it to fit the switch plate. You could use a couple of dabs of contact cement between it and the switch plate if you wish.
I may not be understanding correctly - do you have any pictures to post? Photobucket.com is free, and it's easy to use.
