Further I will keep 1) and 2) above as far apart as is practically possible to minimize Rf interference.! As mounted right now the CDI module and the Rx antennas are 14 inches apart.

Being cautious is always a good thing of course, but to be completely honest, I have been using these ignitions, for about 14 years now in total, and in the time of 35 MHz, there was still a bit of interference every now and then (using PCM, separate circuits and the antenna as far away from the ignition was a must back then), but since 2.4 GHz, I have been feeding the ignition from the same battery, and in some cases the ignition and RX/antennas were less than 8" separate (simply because there was no room... Try fitting an ignition and RX in a Robbe Charter or a Calmato and you will know what I mean), never had an issue with that, EVER.
These ignitions are pretty good, and the nowadays 2.4 GHz receivers are downright amazing with their interference rejection.
If your plane allows, then there is nothing wrong with "distancing", but if it doesn't, then also don't worry about it too much.
Check the date of the video... That plane to date is still very much alive. Distance between RX and ignition maybe 6",single battery set-up, ignition feed straight from the receiver.
