That would definitely be a new BIP.

But firstly it'd make sense to implement it and make sure that the payment processors intend to use it. Like I said, I wasn't very successful so far in getting them to make useful memo fields. I'm hoping that once wallets start actually recording and displaying the memo in their transactions list that will change.

I can probably pick up writing the proposal.

However, I’m not sure what process to follow. Should I format the proposal as a new BIP or should it become part of BIP.70? How does the extensions process you’re working on going to describe the process?
