I'm not sure SDS is an option, unless they've altered their policies in recent times. Ross at SDS has had a really snotty attitude about rotaries in the past.
No idea about these guys, but they do mention 13B/20B support:

And I've seen a rotary-specific controller that I *think* was out of South Africa, but I can't find any saved links at the moment.
Is your MS2 the full-bore Megasquirt? If you haven't tried their forums, you might give it a shot. Someone might be willing to share their fuel/ignition maps, which would at least get you running. If I had to replace an EC2/3, I'd surely look at the Microsquirt.
Supposedly, the rotary, including the Renesis, is included in its options now. It seems to be closer to plug&play than the Mega products. (But no hands-on experience).
