I doubt that SE will make that change. The purpose of the bonus drop is to help the player meet the ilvl requirement for the next duty in the MSQ and the 50/60/70/80 parts of the MSQ have gear coffer rewards to accomplish that.

Have you checked the Manusya Gauntlets of Healing to see if the colors will work with your glamour? It's the same model as the Bonewicca Soother's Gauntlets. With Tower of Zot a leveling dungeon, you would get the bonus drop.
