Inner axle seals

Since inner seal leakage is fairly common on the 8 3/4" axle due to wear on the axle shafts, I was wondering if it would be possible to install two seals in each tube to double your leakage protection.

The first seal in would rest in the normal location and the second seal would butt up against the first. I don't foresee any issues with axle clearances so would this work or am I completely insane?

All thoughts/speculation is appreciated! :)
