Some, but not all casters using alternate spell base?

If an enhancement, how much should it be worth?

If it's an enhancement then it would be 20% of the value of your Magery at most (although that's largely because of the synergy involved in switching from something like IQ to Will which is far cheaper so it may not be worth bothering.)
