Anyone know the rule with regard to the potential change of noun when altering an item? Is it possible?

I have a parka which i now want to be a cloak. Analyse doesn't raise any restrictions.

I appreciate a ring can't be a claid and and shoe can't be a doll. But just wandering if restrictions would be on a case by case/item by item basis or blanket.

{going to do an assist - but just thought i'd throw the question out there}
