I did go through a bunch of gears for shits a few months ago.
across 10 gear sets, different brand, I have over .200" if difference in any direction.
The pitch and attack angle of the tooth are also different. Most will work when mix-matched, but be noisy.
ICS gears have a very different profile and will grind whatever is not ICS (including the motor pinion).
Piston heads also vary wildly. That is because the piston itself does not really touch the cylinder walls, it's the o-ring that expands and seals that does.
Mechbox width is somewhat standard, but finish used (especially when anodized) make a noticeable difference (the Modify TORUS has a hard time fitting in some bodies because of the finish).
Really, if you want to improve what is available on the market, you really should first focus on external limit dimensions. A 3D, precise drawing of absolute limits that "fit everything" would be useful, as it would allow people to design 100% new and probably more efficient/reliable internal component.
I was toying with the idea of a high-speed brushless motor, with planetary gearbox to reduce the speed and boost torque. To get the most starting torque, I wanted to fit the motor inside the mechbox, so that is has a very wide body, similar to HDD/DVD drive motors.
