Double up-shift on Sram X01/XX1? For over a year now I'm using Sram's 1x11 X01 drivetrain. It works great, but the only thing I miss from my 3x9 XTR is the double up-shift on the rear derailleur. With 11 gears it only makes even more sense -- it's often annoying to click the trigger 4 times when starting a downhill section.

I know on the 3x9 XT trigger it was easy to do, as it was almost the same as XTR, but Sram's shifters probably work completely different... Is it possible to "hack" the X01 trigger shifter so it can double up-shift like the XTR?
From what I remember (it's been a while since I've torn one apart), the "up" shifts on SRAM shifters are a mostly passive affair. You click the trigger, and this essentially gets a pawl out of the way of a spool inside the shifter which holds the cable. This spool unwinds one "shift" worth of cable due to the spring tension on the rear derailleur pulling on the cable. The rotation of the spool is stopped by a sear of some sort which catches the spool when the trigger is depressed, and resets when the trigger is released.

The only "hack" I could imagine is to remove or modify that sear, but more likely than not, what would happen is you'd down shift as normal, but pressing the up shift trigger would immediately release all of the remaining cable, shifting you from wherever you are down to the smallest cog. Which sounds completely miserable to me.
