I'd need a coat-of-arms first, though. Which probably means I need to learn how to write blazons, too (although I've still got this idea in the back of my head that it'd be neat to write a program that asks the user a progressive series of questions about a coat-of-arms and uses the provided answers to build up the blazon).
But yeah, it'd be neat. I could have official letters printed and send them to tradesmen, too — "By Appointment to Her Imperial Majesty"... ^^ Perhaps even placques that could be affixed to the entrances of stores and department stores, or otherwise prominently displayed. :)
