So my team is playing with this also, and while the problems of weight distribution are important, we feel that you can get around it because there is no weight limit on FTC bots. While you want to keep the robot as light as possible since power is limited, it also is very realistic to add ballast exactly where you need it using things besides the battery and motors. With a few lbs of steel riding right on the front of your chassis you should be able to compensate to make this concept work.
