Alternatively you can kludge it together. First take the n absolutely horrible 'ritual magic' system in the core book increase casting times by at least two orders of magnitude, them alow players to buy Modular Abilities (Super Memorisation) slots with Preperation Required and Lost On Use/Once a Day. Let them fill these slots with spells they could cast with Ritual Magic but using the standard rolesand taking a -1 penalty for every prerequisite they haven't invested a point in.
