Interesting, as your houserule is pretty much precisely what I'm doing right now as well. When you did it, what character level did you find things broke down at? I'm up to the 4th-5th level range now and so far so good...I used to agree with this. Then we tried playing a 1e game using a houserule that spell slots determined only number of castable spells with no pre-memorization. The casters came to dominate play since they always had the perfect spell. We went back to memorization after a few months.
