An interesting observation concerning differentials. I applaud your imagination and your thinking outside the box. Keep it up.

Your analogy is a bit backwards, but in the ballpark. Some comments.

Differentials do not need to be built with bevel gears. Although bevel gear differentials are the most common, there are other configurations, the simplest of which can be built using only spur gears.

Differentials are most commonly used with one input and two outputs, however they are used with two inputs and one output, just as with you proposed gearbox.

A planetary gear arrangement can be used as a differential and I agree with you, the Thunder Chickens are using it as a differential.

Keep at it. Keep stirring the pot. You just never know what might come out.
