Simple maybe, but inelegant, and still avoids the looming issue of spell list limitations.

There'll still be the shortage of space and when the time comes when the devs want to introduce new spells (or the players want to see new spells), I'm sure the players will become bored of deleting spells just to make room for new ones. It's an issue they're going to have to address, best to simply tackle it at the mechanical level rather than dancing around it.
