Ok on the implications for using the Siren.
Let's try and find out what the bandwidth restrictions are and go from there. I'll take a crack at it today!

*If* the plan is to use the Siren as an SDR engine, then bandwidth is limited to something less than 48k. It's unclear how much if any of the EC processing could live on the Siren alone. Turbo coding almost certainly couldn't.

I'm embarrassed to say I'm totally confused about what the Part 97 or Satellite Service bandwidth restrictions would be on 2m and 70cm.
