How about an ability similar to the clerical way of "memorizing" spells?

How about improvised magic as an option? This should be less powerful than planned magic. It is costed based upon the liklihood of the effect. Things that are likely anyway are easy and strange things are expensive. Maelstrom and GURPS both feature concepts like it. Examples are given for the most common cases (ie. iconic spells) and perhaps combat magic (which must be faster to draw upon both for the player and the character) must be of the pre-baked libraries (Vancian or Powers).
