Have you plugged your gears into a gear calculator to see what kind of overlap etc. you have?
How about after eliminating a gear on each end to allow for cross chaining?
I would imagine with some combinations that there is little gain. Especially compared to a "primitive" 3X9, which apparently has become overly complicated up front over the last few years with that FDER thingy.
