Kind of like how 13th Age does it? Could work, though you'd probably want to give a couple extra prep slots to compensate.I wouldn't change it, and I probably left a comment on why I think it works fine on the thread about setting off traps. But if you do feel the need to change it...
Make them be castable at will, but you have to prepare them with one of your normal spell preparations to be able to cast them--they can't be selected as one of your known cantrips.
Even doing that I expect (based on my experience with allowing people to do that in addition to the normal rules) that players will almost never prepare cantrips. The undesirability of sacrificing a prepared leveled spell for another at-will cantrip is high.
Making them actually use a 1st level slot to cast is basically eliminating them from the game. Might as well make them some sort of ritual instead at that point.
I think they might be a bit more popular given the fact that you don't prepare spells into specific slots - having detect magic on hand is more likely to come up than giant insects if you already have a summon prepped.
