Another option would be try using a dizzy with a VR sensor. A stock one should work, and let MS run the coil from the single coil driver that should be installed. Don't forget to set the options in the setup menu so MS isn't looking for the missing tooth.
You need something to drive the
oil pump anyways, right? Unless you're dry sumped.
I'm running an MDS distributor that has a VR triggering the MS. I use the coil driver to drive a 6AL box, and I have a bypass plug so I can make the coil driver directly drive the coil if the 6AL crapps out. So I have the advance curve of the dizzy, but I can add or subtract a few degrees with the MS. But my setup can not run individual coils because MS has no idea what plug to fire.
Another set up I've read people successfully use it to run a full factory edis system, and let MS control the advance through the SAW and PIP signals. I think this is as good as the MS 4 coil setup I think you were after performance wise.
