Okay, well, here is my final design, which should be coming in a couple of weeks. It's a 1 to 1 replica footprint of the PMS-PD2 (with just the HDMI port sticking out the back) so you can drop it in any design like the Ashida.
Features:
-Converts video from Fuji-flex to USB-C
-USB muxing so it'll give data to your wii, and when its off you can change the files on your drive
-PD charging @ 15V/3A so its fully compatible with the RVL-PMS2
-Same footprint as the RVL-PD so its a drop in replacement for the ashida
-Uses a 19 pin FFC connecter so you can connect it cleanly with your Fuji flex ( and I think the Electron Shephard AVE-HDMI but I'm not 100% Sure)
