Admin Sprites and Rewards?

[notquitehuman]

Is it possible to have it set up so when i give lets say, Developer's access to a character, aka Access lvl of 4, that their character sprite changes into a special sprite set for just admins. Also, is it possible to have it set up where certain accounts are flagged for certain classes? Simply put, could i have someone who has played for a year gain access to a new class on my server, so I could in theory give them rewards for the longer they stay with the game?
