I believe we don't need to include redeemScripts in metadata - they can just be in the properly formatted scriptSigs. OP_0 SIG1 SIG2 REDEEM where SIG1 / SIG2 are replaced with OP_0 if not yet populated.
+1 on the redeem script not being necessary

Advantage of including master public keys in each tx proposal is that the participants don't have to store them as state. This also reduces privacy leaks if a participant is compromised.
The disadvantage of including them is that the tx proposal now becomes more sensitive and might need to protect it more than we would otherwise.
