Fit Gurus: Zipp Vuka Cockpit Fitting Challenges for Tall TP'ers

So...I've got the Zipp Vuka cockpit and am having trouble figuring out how to bring my hands into a more beneficial position for aero. I've got the bike measured up for the UCI jig nearly spot-on, and if I tilt the extensions up, I'll get outside of the 10cm vertical limit from center of armrests to top of aero extensions, so that won't work...Unless I figure out a way to get my armrests closer to the hands and move the contact point from elbow to forearm. And, in order to do this, I'd have to find spacers for underneath the armrests only...so they can stay within the 10cm vertical limit from tops of the extensions....and then I'm wondering how much better/higher the hand position will be, and if the aero benefit (if it's let's say, a couple of centimeters higher) outweighs the increase in stress in the arms and inefficiency that may result...

And, yes, I made the foolish error of buying the Zipp spacers, which I didn't realize raise both the armrests and the extensions together, accomplishing nothing productive (unless I chop off a couple of inches from my upper arms, which I may consider). I didn't add the spacers to the cockpit after realizing what a ding-dong I am, I should've looked more closely at the setup before thinking those would help. :D

This is a fun puzzle. I think. :)

I have a Vuka Evo 110 extensions with a Vuka base bar with this clip/armrest setup (above bar):
