Question for the hardware people: would this help with FIB lookups?
Possibly. It very much depends on what alternate algorithm you use to resolve overlap.
What I'm thinking is that for any given part of the address space, there would be a fixed prefix length. So for 192.0.0.0/8 /24, for 64.0.0.0/8 /20, for 17.0.0.0/8 /8... So in theory, there would be no overlap. There could still be if the filters weren't set up properly, which would probably have to resolved when translating the RIB into the FIB.
