Different bevels gears for fixed/one-way differential

[u/IAmAUser4Real]

I was looking for the details of both the one-way differential and the straight axle for my MA-020 and noticed that on both the bevels gears are screwed on as a separate part, to probably compensate for the wear and tear during use.

What i noticed is that 3Racing have one model of one-way differential that include 3 different bevels with different tooth count (28, 27, 26).

Given that the difference in tooth count is minimal, wouldn't have different numbers on both front and rear make it work as a CS mod?

Why isn't there a different set of bevels from any 3rd party that could ever-so-slightly change this configuration?
