Yeah, I imagine something like the crafting systems in a lot of CRPGs. A sword is made of 3 metal, 1 wood, and 1 leather, with an optional rune slot. Mix and match materials of those types to create one with the stats you want.@Dausuul @Charlaquin raise good points. I want a crafting system to be something that makes my payers flip through magic items & enchantment types like a kid with a bucket of legos or who got the new sear catalog back in the day. 5e made crafting skills almost the default & pointless in that it pretty much just saves you some pointless money in exchange for spending time crafting an item you could probably have otherwise just bought. both 2e & 3.5 had good points to their crafting while 4e made it too easy to just break down some undesired items to make a desired one.
