Im going to go out on a limb here and guess that with efficient weight reduction, you could make a 6 motor transmission that weighed the same amount as the current kitbot one, or slightly more. It's all a question of whether it fits the design criteria of your team's robot.
What do you mean by power? Draining the battery? sure, it does, but any team that makes a 6 motor drive will have considered that and deemed it an acceptable penalty.
You don't need motors for arms, you can use pneumatics, and there's still multiple motors left over if you use 6 drive motors.
