Well if you are bothering to draft up a BIP about that SIGHASH flag,
then perhaps also consider some other SIGHASH flag types as well while
you are at it?
Various proposed sighash types:

"Build your own nHashType" proposal draft:

Also, there was a draft implementation of SIGHASH_NOINPUT:
https://github.com/Roasbeef/bitcoin/commit/4b3c3f1baf7985208ceb6887261ee150ab6e3328
https://github.com/Roasbeef/btcd/commit/67830e506fa135d5239177340918cea39909e6a4
FWIW there was some concern about replay using SIGHAHS_NOINPUT or something:
