Although that would be totally awesome, regrettably not. We aren't using a display ID in the traditional sense for the mobs but instead using code that ties into the Mirror Image code. Perhaps with some further code editing and/or DBC modifying it could be possible, but not with this patch. <E></E>
Try to never just say, "My character isn't interested in that adventure." A lot of people mistake this for good roleplaying, because you are asserting your character's personality. Wrong. Good roleplaying should never bring the game to a screeching halt. One of your jobs as a player is to come up with a reason why your character would be interested in a plot. After all, your personality is entirely in your hands, not the DM's. Come up with a reason why the adventure (or the reward) might appeal to you, no matter how esoteric or roundabout the reasoning. -(Source)
