A different plate. One person bought aluminum plates during one of the GBs I ran, then used a dremel tool on all the correct edges to widen the holes until the matched.
Once she posted the picture of the completed keyboard, she said "Don't do that. That was dumb." Or something similar.
Some DXFs are floating around, but someone commented that the stab holes would technically need to move a fraction of an inch to match the new, accidental switch location.
Oh and this advice is for the traditional, Teensy operated ergodox. It might work with the infinity boards too but you'd want to make sure the electrical paths are separated the same way, since technically the fluke relies on an engineering choice not at all related to cherry MX switch holes.
