throttle valve cable geometry

Hello fellow 3rd gen hemi swappers.

I have been researching the best way to attach a throttle valve cable for the 200-4R transmission I am running behind my 5.7 hemi. As I will be running a megasquirt based system, I will have to go to a cable throttle body. Pretty much every cable conversion hemi throttle body out there is $350+ without the TPS or AIC included. My current idea is to make an adapter plate to run a stock 80mm 3 bolt LS motor cable throttle body on the 5.7 hemi intake manifold, for which bowtie overdrives makes a kit under their EZTV name. Everything I read about these transmissions says that the geometry of the throttle valve cable is extremely important to the life of the transmission. This would allow me to ensure I have the proper geometry and be able to use a much cheaper cable throttle body. EFISource has also assured me they can build the hemi harness for the Gold Box megasquirt kit with the GM TPS and IAC connectors on it as they already build an LS kit.

My main questions are, does this sound feasible to you? How did you run your transmission linkage if you were using a front mount throttle body? Got a better idea?

Thanks for any and all help,
