Merged mining at present only needs one hash for a merkle root, and 
that's stored in the coinbase. It would be even simpler to add the 
following rules:

1) No OP_RETURN transactions allowed at all
2) If you want to commit data, do so in that one transaction in the 
coinbase

Also curious about how you'd handle the payment - do I need to put in a 
transaction that burns bitcoins for the tx fee? That isn't free in terms 
of storage either.
