SPV is for checking validity of transactions that have already entered
the blockchain, as I understand it. My proposal requires nodes to
validate transactions that are unconfirmed, and to commit to the
validation by doing a POW on it.

If we stipulate that the coinbase fields only hold space for a single
pubkey, then the entire block header including the two coinbases
should only take an extra 100 bytes or so. Transactions are already
routinely 250 bytes+. So an increase of roughly 33%.
