Ordered and received a replacement switch. Just as I described above. So that method definitely works. Its nice to have my MVS working again. I also compared the 3a push button switch used in the RS to the mountain switch the MVS uses. You'd have to enlarge the hole to fit the switch and its just long enough that if you spread the legs on the switch its right at the spot where the plastic end cap sits. So I think you could shoehorn in the higher amp rated switch but there will be no free play at all because the switch is enough longer compared to the mountain switch. And there really is hardly enough space in the top to accomidate the larger hole.
