I think crafting requires an overhaul. I believe that this adjustment would make all drops of all weapons potentially relevant. When a weapon drops, it not only unlocks it in blank weapon frame in collections for that weapon. This blank frame is the base for the crafting and you use it by infusing another of the same weapon to gain a barrel/perk in the frame. As an example, Weapon A drops and the blank unlocks. Another Weapon A drops and it’s has Arrowhead in the barrel that you want for your god roll. You go to the frame and select the Weapon A with Arrowhead and then select that barrel and infuse. Your blank frame now has the barrel Arrowhead on it. So on so forth. With each drop of Weapon A you can update the frame in collections. Once you have your perfect frame, you collect it from collections and it goes to your vault as a usable weapon. With each weapon having 5 slots in it (barrel, mag, perk 1, perk 2 and masterwork) You would need a minimum of 5 drops (just like now) to unlock the perfect weapon. Each drop is relevant as you can change the frame if you got another Weapon A with a different perk should you want to. I also think this would deal with the vault space issue.
