Also make difficulty proportional to object size and value? The player's relationship with Cleptia would definitely factor in as well.
Definitely.

Would it need a cool down?
I don't think so as long as you cannot always steal successfully. We could cap it at something like 80 - 90 %, so there's always a real threat of being seen. With no cooldown, it would then seriously tempt the player to steal only one more item.
EDIT: Also shopkeeper's Per should play a role.
I now have a mental image of player using a pet bear (who is enormous) to block the shopkeeper's line of sight to steal...
