I'd like to edit some stats of pre-enchanted items, but they're greyed out. Is there a way to unlock them?
I'm creating a weight overhaul mod, specifically, and I want to change the weights so they match the edited values of the unenchanted stuff, which I've changed no problem.

you need to change the base template.
OR click the template dropdown box and set it to none.

Basically the weapon is copying the stats off another weapon, (from its base template)
Find that weapon, and edit that one.

personally i recommend editing the base template, instead of setting the template to none.
