The idea I propose is to do a few things to enhanced perks when the weapon is adept. Make it so enhanced traits that already get an improved effect, either make it have another bump to the effect or add a new small benefit, Gutshot Straight could provide a small benefit of more damage to the body or a 10% increase when a headshot is landed. Traits thay only provide time extensions could provide an increase per stack of the effect. Be i encore, rampage, etc. Finally traits like Eye of the Storm that only add a stat could actually increase its effect by 5 to 10%. When both traits are enhanced then the origin trait could also become enhanced and provide a minor increase in effect or time of said trait being active.
