I planned to do an outfit set model morph depending on where the player is, without unequip and re-equip a piece of armor. so wanted to know if this is this possible...before I try to do all the code, then get stuck on a dead end. like the last time...

No, I'm pretty sure you can't swap the mesh associated with an object via script. The closest approximation would be to swap one item for another.

It's possible that SKSE might make this functionality available in the future.
