You can't really get power distribution like that with diff fluid changes. All the center diff does is allow different rotation rates when the front or rear are in different traction situations. In other words, if the front tires are slipping, heavier fluid will help slow the slip by keeping them more closely matched to the speed that the rears are turning. Lighter fluid would allow an easier transition or differential between the fronts and the rears. Hence the name differential. Same thing with the front and rear diffs when comparing the available traction or turning radius of the left and right tires.

Using different weights front to rear only changes how easy each of those transitions occurs between left and right on it's respective end.

In a perfectly straight line, with good traction at all four wheels, differentials are basically not doing anything. They could be filled with cement and work the same. (assuming that the gear ratio front and rear are the same)

Now if you wanted a differential in the speed front to rear, that is what you would need is a different gear ratio on the front gearbox from the rear. Mugen had that in the 5R I believe.
