I'm afraid I don't follow your logic here. Speed of a drivetrain is more dependent on motors and gear boxes than anything else. As far as I'm aware the wheels shouldn't have too big of an impact (except for size of the wheels, but a traction wheel of the same size won't be any different than a Mecanum wheel). You are correct in that pushing ability is greatly reduced by having mecanums, but speed is not.
