Possible gear evolution after a certain level

[XP_HAVOK]

So throughout the games we get and make better stuff while our weapons remains the same except mod changes. My idea is after a weapon hits a certain level it can evolve like the pipe weapons aren't really good but what is after level 5 or 10 it becomes a steampunk weapon and gets more accurate or if scrap boots become bunker boots and have more defense or such and so on. It would make longer games more fun and have more weapon mods that could be more stylized. It can even make some of the older gear more useful like the blunderbuss becoming a mini cannon so no weapon or gear becomes forgotten.
