For instance it would be near impossible to snap the 2.77 pinion on the auto's 8.6 ring and pinion setup. But if you went to say 4.10 or 4.33 you would be looking at 40% reduction in pinion size and then it gets that much easier to lollipop the pinion. The old 10 bolt 7 and 3/4 tinkertoy rear with 2.73s had about the same surface area as a 4.11 in a Ford 9"... all in all there is little reason to spend $500 on the gear as there is no direct performance advantage.
I don't know how the 1LE will do in the autoX I'd think it would be a leave it in 2nd the whole way... out of the exit at 34 MPH the engine would be at 2750. I can see a cam with close lobe centers around 110 with 230 duration and maybe LT 1 and 5/8 to bring up the midrange, definitely would do the ported stock intake manifold for the much stronger 3000 to 5000 torque.

Sorry, I thought oldman was saying someone did...
Had Richmond 3.73's on my 5th Gen and was very pleased with the results.
