Oh hehhe. I created several custom guilds on my server based on real guilds I interacted with over the years. I even did all their emblems, and colors to match. Only thing missing is their tabards.
I totally think it would be super awesome to see bots running around with tabards on sporting their colors.
Even for the random guilds the server generates, I'm sure you can come up with a nice set of tabards based on say 20 or so templates you input in to the database.

You're welcome for the idea. I've just never seen any bot repack include tabards as part of the bot inventory. The immersion would increase a lot. <3
Here's 27 of them from my server if this helps you at all. They are quite nice looking. Some I think are me just randomly putting values, as I ran out of guilds I knew, but a good portion are good eye candy.
