Heh, interesting idea.
Now what happens if someone who is strong enough to lift the statue casts meld into stone and moves into a wall or cliff face, drops the statue, then exits the rock.
What happens to the dropped item? And how tough is it to find the statue? Could the statue be dropped far enough inside the rock to block some of the various divination spells that are blocked, let's say, by 1 foot of solid stone? And because lead is a mineral, could the person who melded into the stone reach further into the rock, right through a thin sheet of lead, in order to drop the statue there?
Heh-heh, I like this idea of not actually killing the person quite a bit. It even means that the bad guy can bring the creature back to life and there's no chance that they can refuse to be "raised"...
