Morse mods?

Been cooped up for weeks and I’m getting bored.
I’ve been playing my standard Morse quite a bit, and the “add bridge” switch is bugging me.
It’s fine quite a bit if the time, but when getting into funky rhythmic stuff, it’s really in the way.

So I’d like to mod it a bit as a project. Partially just for something to do.
But I’ve never modded a guitar myself before, and I don’t know if what I’m thinking is going to work.

What I’d like is to remove the “add bridge” switch altogether. Then put in a 5 way switch instead of the 3 way.
I know these are both doable.
The next part is what I’m not sure of.

I’d like to use the 3 position switch that controls the slanted pickup as an “add bridge” in the down position, off in the middle position, and “add slanted single” in the up position.

I may also look into changing the humbuckers as well.

Any thoughts on if this would work?
Any advice for a novice modder?

I picked up Dan Erlewine’s book, and will be doing a lot of reading as well, but I’m always glad to accept advice.

Thanks gents.
