Control of 2 cameras from single lap is a problem I haven't solved yet...
The setup on attached picture is put together just as feasibility study.. it will be much more stable and rigid at the end (I hope..)

Impressive setup. Is that transportable though?
Is 1000mm too long or just right? With APS C that is more like 1600mm and that would be quite a magnified view. Perhaps its just right - I am not sure. I used 600mm with the Venus transit and full frame camera and the sun could have been a bit larger. So perhaps an APS sized camera and 600mm would be a nice size. I'll have to test that.

I suppose the key thing here is to practice with it well in advance and iron out any bugs.
Is 320mm a bit short? It might be fine with an APS sized sensor.
A PST gives good Ha images?
