Reply to Custom APC80 Build

Hey there,
I've been lurking for a while and decided I should probably join this wonderful community.
I've recently built an APC80, and been working on a custom version of Will Marshall's template.... My vision is a "battlestation" of sorts...where two dj's can battle back and forth.... I'll save the controllerism questions for that section, but I wanted to share my build, and the changes I made.

I wanted this to be like one instrument... 1 usb cord, 1 power adapter, and one sturdy controller to carry.
As far as sturdyness... I added washers to the main bolts that hold the two controllers together, and used 2 aluminum bars instead of a large plate. I also plan on using Sugru (https://sugru.com/) to fill in the gap, and hopefully eliminate the seam between the controllers completely. Supposedly when it hardens, it has the adhesive strength of super glue...I'm looking forward to that.
For 1 USB cable, I'm actually using a 2 port in-line usb hub(amazon, $10), with one longer and one shorter cable, and the entire hub and connectors have heat shrink keeping them from separating. This part is currently in transit, but I'm using a different hub, and have had no problems with 2 controllers on 1 usb. This part is essentially a 'usb Y cable'

Power was a bit trickier, but I believe I've developed a clever solution similar to the usb fix. Both the APC20 and APC40 run off a 12v 2a power supply. I've ordered a 12v 4a power supply, and plan on making a Y adapter, running both plugs in parallel. I will put 2A fuses inline just in case, but this power adapter is a laptop style power brick, so I will connect both apc's, turn the switches to on, and then plug the power brick in to avoid any chance of 4amps hitting one of the controller.

I want to change the crossfader out...I see that its removable, replaceable, but is it cross compatible? Anyone have any idea of any other crossfaders that would fit? I'm specifically looking for one with a notch at center, and a bit more resistance than the akai one

And no build thread would be complete without pictures...admittedly I am a bit of a Red Bull fan... The last pic is just a little teaser of something I'm working on..more details of that to come
