I pretty much agree with Mighty Buzzard.
Remember that a lot of the more extreme effects of magic (compulsions, transforming an object or person into something else) can easily require dozens of shifts of effect (enough to fill up all the target's consequences and take them out) as explained elsewhere on this forum.
So, yeah, what you're talking about it possible, sure, but feasible? That's iffy unless you're really powergaming.
