It shouldn't be too hard, I suppose -- I won't have you come up and speak to the audience, and you'll mostly be at a distance, so whatever you do won't have to hold up to the closest scrutiny, though some of the guests may bring binoculars or the like. I imagine Lieutenant Violetta can get you a suit of Royal Guard armor; I'll trust you'll take care of the details."
