My team has used drivetrains that use only two CIMs for as long as I can remember (exception 2004 when we used four gearboxes) and we know that being torque limited is a major problem. In general our only problem was overheating. In the past we dealt with this by making heatsinks for the CIMs so as to prevent them from over heating. In my opinion how you choose to distribute you CIMs really dependes on the challenge.
