Did you guys do butterfly / octacanum? I don't have empirical evidence to back this up, but I would be tempted to say your drivetrain is loaded a lot differently than a typical 6WD and thus things might be different. The drive style lends itself to avoiding defense more than trying to force your way through it. The omni wheels eliminate turning scrub which is a large source of high current draw in tank drive robots. I believe you guys also did 4 CIM / 4 mini, but that shouldn't be a *huge* difference over 6 CIM / 2 mini.
With a gearbox like this, it's certainly trivial to add one more mounting hole and just experiment with it, particularly if this is being built in the off season. I expect 6 or even 4 motors might turn out to be better for performance at a variety of FRC speeds, but there could be something I'm missing here. Did you guys notice a particular advantage to 8 versus 6 motors? (I'm not sure if your drive lent itself well to a number of motors not divisible by 4 so I don't know if you tried 6 CIMs or not)
