I agree that the banner is really the one to use, the question is on which model.
The silver helm horse is, I think, to identifiable. I am seriously considering the "Turkey" standard, but I think it will naturally convert into a dragon. I'm thinking of sawing the middle, splaying the wings and scratching a leathery wing pattern into the back.
The champion is really the difficult piece because the temptation is to use the dragon helmed hero and call it done, but I just don't like using duplicates for important pieces.
