What your asking is a like if i wanted a low tr4 armour/weapon being a high tr3 armour/wepon in a sense.
If you really wanted this i would think a nerf to all SHC's would be put on to make them about the same stats as Heavy Barricade. (It same crafting btw)
As most people will say no this idea is not needed.
Only thing that could change is Big ammo as normal amo all can bring and a buff of speed and being able to bring 3 more is not worth the jump from Everyone to Engineer.
Even then you get 1 more ammo box for each lvl it's not too bad.
