I think you could generalise that slightly and make it fit in with the existing opcode naming by calling it something like "OP_CHECKTXDIGESTVERIFY" and pull a 33-byte value from the stack, consisting of a sha256 hash and a sighash-byte, and adding a new sighash value corresponding to the set of info you want to include in the hash, which I think sounds a bit like "SIGHASH_EXACTLY_ONE_INPUT | SIGHASH_ALL" FWIW, I'm not really seeing any reason to complicate the spec to ensure the digest is precommitted as part of the opcode.
