How about giving each alliance some more discs (55 whites per alliance instead of 45, for example), and allowing each robot to carry 5 discs instead of 4? This will allow higher scores and more interesting shootouts. You could have 30 discs in the air at the same time! I think allowing an extra disc per robot would be more interesting to watch. It will also make defence more valueble.
Also, most teams have room for five discs or need very little work to allow five discs in their robot, so it barely gives any design an unfair advantage, except for favoring faster shooters, which is not different than the original.
