If you go to electronic timing, then also do coil on plug or waste fire coils. Crank trigger the ignition, and one pulse from distributor for TDC sync. Then no need for rotor.
That is the best idea and what all current engines use, as far as I know. Indeed, I already installed a 36-1 trigger wheel on my 65 Dart 273 crank pulley to later use a Ford EDIS ignitor.
However, I don't read that the Commander 950 can command EDIS timing. It can control earlier "computer distributors" - Ford TFI and GM 7/8 pin HEI. The later w/ interface cables came with my Commander 950. I will probably try that on my 383 since I don't see an easy way to install a trigger wheel on the crank pulley. Sparking off the distributor is probably good enough if the cam chain is tight. It was used until 1995 in GM trucks. The Commander can also react to a knock signal, like from a GM ESC module.
