You can't use 6 cims in present mecanum drives.

Your calculations are totally dependent on weight. Acceleration on a 90lb robot is fine. Just look at 254 to see very sucessful drivetrains that have been geared fast(16-18 fps).
While you can't run a 6 CIM mecanum, you are ignoring the fact that at this weight and complexity you might as well make an octocanum or swerve.

Controlling a robot through 4 independent shifts on a mecanum drive would be difficult.

Teams do it all the time on butterfly. Mecanum is no different.

8 years ago if I told you that in the future, mecanum wheels would be available for purchase to every team at a reasonable cost, you would have called me crazy.

Honestly I have no idea what will be available in 8 years, so it isn't worth speculating about.
