What kind of current can the connectors handle, and what type of connector are you using? With all those pins, the possibility of a mechanical failure grows esponentially. Also, you will have to worry about interference between the different calbes, and the wires that compose each cable. 80 wire ata cables use a ground between each data line to reduce coupling between each data connection. What type of shielding do you have? Sorry to be negative, but i wouldn't attempt something as fragile as an integrated connector. Waaaaay to many mechanical failure points.
