Gun upgrade perk system expansion?

I really enjoyed the perk system, but the final level felt a tiny bit empty, is it possibly by any chance to shove up the levels a bit? To make place for a new blue armour upgrade perk system?

One where instead of upgrading your abilities, you choose an upgrade for a specific weapon class.

This would compliment legends to explore playing a certain way with a specific weapon class. For example rampart getting the option to upgrade her LMGs or Snipers. Switching up her playstyle from using mostly LMGs to building a fort and using the damage AMP from the walls to boost her sniper.

I made a list of all potential weapon class specialization perks for each legend down bellow. Maybe it’s a fun concept? I’m not sure. It’s the same theme that mad Maggie has.

Here’s some ideas for what the upgrades could provide:

AR: Faster reload

SMG: Faster reload

LMG: Less recoil

Marksmen: Larger magazine

Snipers: Larger bullet hitbox

Pistols: Larger magazine size

Shotguns: Larger bullet hitbox

The 1 indicates which legends get upgrades to which legend class. For example Pathfinder get the option between the Marksmen weapon upgrade and the Sniper upgrade. This is because his grapple allows him to easily aquire highground to get a shot on enemies.
