The grand company Elite gear that we can obtain from the hunt master is very exclusive, I almost never see anyone wearing even a single piece.

One possible reason for that, IMHO, is the class restriction on the gear. I understand that the existing set is level 50 gear, but it's actual stats are obviously out-dated so it will only ever be a glamour.

I suggest adding a second set of Grand Company Elite gear to the Huntmaster, specifically as a glamour set. This glamour version would be a level 1 item with basic defense and no bonus stats. It would have no class restriction and players would be able to dye it. The cost should be the same amount of Allied seals as for the original piece, plus the original piece - since this in effect an upgraded version of the original.

I think this would invigorate the hunts for a while at least as well as perhaps giving these looks new life in the game. Plus I would totally spam hunts to get most of the pieces from the Flames for glamours - especially if I could mix and match across classes.
