Right before I left home to go visit my mother, what I was working on was adding Raid pivots to an old ('50s) fork with a crown that's narrower than Raid bosses "want" to be. To put the posts 75 mm apart, the miters were going to be partial, as in having an opening on the sides, because they're so much wider than the blades. Maybe I'll miter them more on-center with the blades to get full contact all the way around, if the brakes work just as well. That bike will have 42 mm tires on narrow rims. Will the brake still let a 42 out? I can test it easily, just mount the Raid arms on a Racer étrier, so I guess I'm just asking in case you know off the top of your head.
They work just fine, and I've got 35mm wide tires on my Pro Tour, no issues getting the wheel out and catching the tire with brake pads. You'll note on the picture that I did mostly "choke up" the posts on the slotted arms. I've never run fenders on that bike, but I'd bet that the arms would catch on a fender and limit how far they can swing out. It'd be doable if you didn't mind the dreaded "let the air out of the tire every damn time the wheel comes off" syndrome.
As for the post/fork interface, I've brazed a lot of them onto early 70's Raleigh Competition forks, which aren't super narrow, but no one would call them wide. Instead of keeping the outter part of the post/fork interface open, I stuff some brass up there and build up a fillet. After filing and blending the curves, if you look at them straight on from the front or back they look a bit like the bulbous tail lights of early 60's American cars. I usually cheat a few mm on width from MAFAC spec.
I learned early on that the pre-mitered posts aren't worth buying, they never match up on the fork, so I stock the unmitered ones and hand file them.

Come to think of it, I have a set of one o' them eclairs or whatever you call them from a set of RAIDs. I wonder if he's still wanting them.
For one set, probably not. I did spend a weekend cleaning up and polishing the pastries before sending them up to Seattle.
