DROP DATABASE is a rather costly task.
I would UPDATE a one-row table periodically, setting a column to NOW(). Then read the value on the Slaves.

Production servers should not show significant degredation even with dozens of slaves. How many do you have?
The Master does little other than keep TCP ports open to the slaves (one per slave), and write to each port as needed. Unless you are saturating the network bandwidth, the Master should not be significantly impacted by lots of Slaves.
