Shaving down Start and Select buttons?

In the old Himura Games guide on modding the Hori T5 there is a part about shaving down the Hori start and select buttons so the plunger is recessed. Would it be possible to shave down Sanwa or Seimitsu buttons in a similar way? Anyone have experience with this or have a pictures of the underside of Sanwa and Seimitsu 24mm plungers? I’m finally getting around to modding my dusty old T5 but I’m trying to figure out what to do with start and select before I order the buttons. Thanks
