Double Modifiers for on-foot gear

Following up on my "Hotkey wishlist" thread... it got me thinking about other quality-of-life or experimental features that FDev could try... maybe in Test servers, that would probably require little development time. My idea - allow to have multiple of the same modifier on on-foot gear. Make them have diminishing returns to prevent outlandish stuff.

Why? Because on-foot gear has pretty narrow build options already. How many flex-slots do you have on your combat suit? Faster Shield regen and Increased Armor are auto-includes. Increased Air, increased melee, quieter footsteps, combat movement, enhanced tracking and reduced battery consumptions are useless. Extra backpack is good for Maverick when raiding settlements but that's it. Night vision and Jump Assist are OK I guess, but that's for when you don't have any other things to add. Ammo boxes are everywhere, so it's not like I ever need extra ammo capacity either. I'm left with Increased sprint duration and Improved battery capacity... and I guess that's fine

But what if...
What if I could get 4 Added Melee damage for 193% added damage? Throw an EMP granade, and run in SMACK SMACK SMACK juggernaut style. 1-shot melee w/o shields.

Or how about...
400% increased sprint duration. You pretty much zoom the length of a megaship deck during OP without a sweat! might catch some stray bullets, but with time-sensitive objectives, maybe some teamplay where other CMDRs provide cover, this could worth it! or at least fun to run.

Some options would need some major math and balancing - like increased armor resist or reload speed/headshot damage on weapons... but it would open so many more options. (although weapon engineering is way better, outside of improved hip accuracy and faster handling - I use all of them)

that being said, I think Odyssey Engineering for on-foot gear could be more spicy...
And maybe some more guns while we're at it? kinetic shotgun? laser sniper? a grenade launcher or mines to be placed in corridors?
