Would need to do this with a lathe or mill. Hand sanding/filing won't be able to plain it straight.
I'd be interested in seeing if anyone has a solution for centerlocks.
Your only option likely is just recenter the caliper every time you switch with the two M5 bolts. It shouldn't take more than a couple minutes to realign it, although the big issue is pads wearing quicker since they have to rewear onto wheel swaps.
