Headlight Toggle Switch?

Good morning!
Building a custom gauge cluster and was trying to come up with some work around for the headlight switch. Looking at the diagrams, it looks like the full 12V runs unfused through the factory switch? Has anyone ever replaced it with a toggle? If so, what amperage would that need? I was considering the same for the wiper switch? Its a two-speed so maybe and On/Off/On? A quick search didn't come back with anything.

Not an electrical engineer, so don't even know if this is feasible.
