What if you could use a glow sack, and a dye of your choosing to change the sheen of your enchantment? Instead of the admittedly lovely purple, now you can have any color of your choosing! This would bring a nice amount of customization to the player's hands, and would overall be a net positive change. Also it would give the glow squid a good use, and may repair it's ruined reputation. Just a thought though.
