The video games have a much larger selection of characters than the current official toys. Just look under Batmans' bio and you'll see them.
I was curious and checked the E of bay to discover some customs. Booster Gold had a couple but only one really looked like the costume. Starfire has some based on the cartoon and only one that actually looks like the comic character. As you might have noticed Jason is the only one from the main bat family not accounted for (the bigger Robin they sell is Tim) despite the demand. The customs are pretty pricy usually around ten, twenty or higher.
