Token Exchange for 24-man Gear

For 24-man raids, getting a specific piece drop is really annoying. For example, I still haven't even seen the tank body drop for Orbonne. I have a bunch of coins from each of the SB raids I'm not using, so I thought it would be a cool idea to be able to buy gear with the coins instead of letting them rot for all eternity. I'm not sure if it's feasible, but it would help the glamour grind so you don't go for years without seeing a piece

Side note, something like that would be cool for level capped dungeons too, but I know that would be difficult considering we don"t get tokens. I legit farmed for the plaguebringer coat on and off for over a year and a half after it released until I got it.
