Swapping CAS for Dizzy

I've never heard of anyone being able to do this with the stock ECU, nor do I understand why anyone would want to...

That said however, I do know that when the earliest Megasquirt kits (a DIY EMS) came out, it could only control fuel on a rotary, so the easiest path to full fuel + ignition was to have the MS handle fuel and swap out the CAS for a dizzy from an FB for spark.

The current crop of Megasquirts are capable of full rotary ignition support, leading & trailing, at least for the 2 rotor engines. Don't know if they can support ignition on a 3 rotor 20B though.
