Issue is, heat is the highest entropy form of energy. If you wanted to “create cold” you would need to convert high entropy energy to low entropy energy (pretty sure that’s impossible), convert energy to mass (probably impossible), or outright destroy energy (impossible).
Personally, I think marking outfits would be really neat. It might be easiest to just have a build-able marker for “outfit piles” and activating them would swap appropriate clothing with what you’re wearing. It could go through and check each of the clothing items on the pile, equipping them if there’s nothing worn in their slot, or swapping them out if there is.
