Actually, falling asleep last night I realized what I proposed would be yet another variation on an 'anybody can claim' transaction (anybody can just choose an r1 that make r1 XOR hash_xor_r1 evaluate to a hash that they own).

I think this would work:
... supply <scriptsig> <public_key> <r1> to claim.

I'm not suggesting anything like this get implemented any time soon, I started this thread just to explore what is possible.
