Conversion of 4.2l F250 from digital to mechanical

[afterhours]

I have just purchased a used 4.2l F250 (motor only) that requires digital throttle/shift. I have no problem with digital controls however my current setup uses a dual binnacle 704 with an OX66 250 and a t9.9 (remote, power tilt, electric start) connected to the binnacle and key switches. The T9.9 steers with the OX66. This is an awesome setup that I will probably have to do away with if I use digital controls. My question is if anyone has experience converting the digital version (F250XCA) to the mechanical version (F250XB). That way I could keep my current setup. From the parts diagram it looks possible but? An alternative could be to buy the single digital and take the guts and put them inside the 704 case, residing side by side with the mechanical control for the kicker. Anybody have experience with this?
