Roll 21.
AW/E/D can be simply kind of spells.
You prepare them as you like.
When you cast a daily spell, you lost that spell(till you prepare it again).
When you cast a encounter spell, you need some fix with that spell(or short rest, in 4e term).
When you cast an at will spell, well, you recast it as you like
So, you don't need feat or whatever.
Maybe this is too flexible.
Then, restriction by slots can be introduced.
Say, wizard has mostly daily slots(you can prepare daily spells only with them) and only a few encounter/at will slots.
Sorcerer has mostly encounter slots and some daily slots and at will slots.
More idea:
Wizard has daily slots only by default but can gain(or exchange) encounter slots(if you're ok with feats).
Sacrifice daily slot permanentlly to gain encounter slot.
You can choose to prepare each spell as AW/E/D.
(Way too flexible ?)
You can choose to CAST each spell as AW/E/D.
(When you cast as E, you can't cast it until you fix it/You cast it as D, it's lost)
Spell with long duration can be "prepare and you gain effect" spell.
(I ambiguously remember such spell in 3e era...?)
Say, you prepare "eldritch armor" spell, and you gat +2 to AC. You don't need cast it; actually, you can't cast it. As long as eldrich armor is prepared, you have that bonus. But one slot is used.
When eldrich armor is dispelled, you lose the bonus. But you can regain it as standard action.
