Progress!! I used King Casey's method of bending the frets. It wasn't exact, but it worked. I've installed all the frets (I had exactly enough wire thankfully) and it went with minimal issues.

The frets are not sitting completely flush though...

Hopefully you can see it, it's hard to photograph.

They are very close though, I can slide a piece of paper under but not a folded piece. They are also very uniform, all of them at pretty much the same height above the fretboard. Some of them have edges sticking up but I can sort those out easily.

I am happy with how they are seated but want more opinions. As long as it won't cause issues, I'd be happy to leave them as they are.
