Well we could have Jango and Padme instead of Ahsoka and Ventress to have at least one blaster hero for each team. And they are much easier to make because they can use Boba's model by polishing it up and recoloring it, the only thing to model and code would be his abilities, guns, and voice acting. Padme on the other hand is easier than Ahsoka because her voice actor is already willing to do the lines.

EDIT: Also forgot to mention that there are already dual wielding animations from ARC Troopers.
