Definitely late to the party on this one.
All above sounds good.
If they restrict your mods beyond the written, the deflector in front of you and the "headrest" difuser would be your best bets.
Careful on enclosing the cockpit. It would be safer to use lips to direct the airflow.

Look at the current F1 cars for more ideas.
