I like it too.
My gaming group has always had a bit of a liking for the idea of adding items to gear to improve them e.g. putting better tyres on a vehicle, putting a better scope on a rifle and so on. Basically a way to let a Character improve their chances with a Skill check, especially if they are not particularly good in that Skill.
If I can con my group into any game using the 2.2 rules, I'm very much inclined to use your idea Swaghauler
