For aesthetics it's really cool. The vios and such change the shots to a magenta hue in some weapons so maybe to avoid confusion the boosters can instead have different particles from the gun.
Like how the violent booster has these particles orbiting around it.

Maybe make the gun have an animation around in a similar fashion to the healing effect

You are still able to visually see someone is using a booster and in case it's not wanted then the small detail of the magenta hue on the shots.
Besides that, some weapons already have their own colours like the peacemaker's green. Would it be hard to change the colour of the skills as well? It would be very cool to see the fire from a colt with cyan or a red lazer blast of the peacemaker. Over all good idea ^^, hope the devs see it
