Oh definetely! I'd love to have the hood for the WHM AF1 body piece (Healer's Robe) be able to be raised (enemy undead WHMs in Lost City of Amdapor HM actually have their hoods up like that so the model actually exists!) for a start, but the big one I'd especially love this sort of functionality to be added is the Sophist's Robe, gained in EW's storyline - specifically not just being able to raise the hood but also wear the mask as well (sure you can wear an existing mask with it, but as the robe already has a mask hanging off the front of the wearer's chest, it looks rather redundant and silly doing so).

Of course it would probably be tricky to get working so as not to clip with headgear the player may actually be wearing (or adding to client/server processing by adding extra requirements for the client to hide headgear while the hood is up), but it's something I would love to see added (to say nothing of the part of the game that item was actually gained specifically requires the hood and mask to be worn down for lore reasons in that particular area, but I digress).

Please Yoshi!
