Maybe if there were semi-static rolls, such as a gun having 3 possible perksets, and each one would modify how the weapon was meant to be used. Example: Tone Patrol- Set 1: perks a+b+c+intrinsic Set 2: perks d+e+f +intrinsic Set 3: perks g+h+i+intrinsic The perk set would be determined upon getting the weapon, and it would not be changeable, other than going to the gunsmith and using some new material yet to be introduced (maybe like legendary Glass Needles, which cost 50k glimmer a piece, or very rarely, finding them after the raid.)
