The 6v switch will be ok for the long term. The limiting factor isn’t voltage as much as current. Since the current will be lower at 12v it will be fine.
That said, running all that current through any switch is not the best way to go. I installed headlight relays in my 48, one for low and one for high beams. The current through the switch is just a few ma.

I installed relays and circuit breakers on my 48 when I put the halogen bulbs in.

then the whole debate in the headlight switch is done, you only have a few ma running through the switch. You could use a micro toggle and be safe.
