Cute but impractical: There are plenty of thrown spells with better tradeoffs than 5 ST for 1+0 damage. Though I guess destroying the staff would be of some use. Casting it on someone's earring could be more upsetting. Destroying a power stone would make you very unpopular during the post-battle loot-the-bodies phase.

As a variant on your idea, have you considered casting Staff on the enemy wizard's Staff? I think the rules are sufficiently ambiguous it could do almost anything.
