Well after reading this post. I got the inspiration to do it myself. Who do you think can provide dimensions ? Maybe an overall design
I have friends that do carbon. They are part of the local rocket club. And I already discussed with them. They are ready to help.

 

ensure ducts are adequately placed along the exhaust, blocking off air flow for aerodynamics does speed up heatsoak on the pipes and chassis!

 

Understood. Ok let's make this a little interesting. If anyone can come up with the design for this project. I will give our prototype for free. Anyone that participated will get a special discount.
