Sky Piercer heirloom customization

Can we get an option to change the power source / glow of the sky piercer heirloom ? It's already a thing in the firing range, you can get a bug to have the glow from another variant of the heirloom and it looks really cool, plus they already have the UI made for the katar heirloom so why not just give the option directly in the menu ? I uploaded a few examples so you can see how cool this looks.
