design is no different from a regular seymour
but, BKP ceramic models usually have the 4mm thick magnet
I suppose the alnico warpig has a 3mm magnet
so, you'll need thicker spacers as well, or you could try a thinner ceramic bar that won't make it sounds pretty like c-pig
you better ask tim first and aware that you'll lose warranty
removing the cover might get tricky, but no big deal
take out the solder points between the cover and baseplate
than use pliers between one of the pickups leg and the cover edge to push the cover out (by spreading the pliers legs... do not try pulling the cover by the edge with the pliers or you might damage it)
one side at a time, no simultaneous force needed
