MSD for rotary CAS possible?

I was just wondering if there is a way to hook an msd ignition box to a stock CAS. For distributors i understand completely. If the msd box doesn't work, what setup or system is out there to amplify the spark of the CAS/coil to the plugs like an msd does?

You can't connect it directly to the CAS. Well, you can, sort of. Since the CAS triggers twice per rotation you could run leading only with fixed timing. That of course is pointless.

You can connect the MSD box between the ignitor and coil. Most do leading only. However there's no real point unless you are running high boost, rich AFRs (which is an issue in itself) or some form of auxiliary injection. The stock FC ignition is quite good.
