I couldn't help but MARVEL at this idea when it came into my head. Though some of you might find it a bit STRANGE, I think that it will make a wonderful addition to any comic-fan's arsenal of poses.
To create the spells, just have a friend use ruin then shrink their model and bring the alpha slider to 0. It will make both the circle on their hand and book remain. Then it just takes a little creative positioning/scaling to make it work!
