Thanks. Here is a structure that would help me to help you :)

 1. Introduction
      * Problem statement: Say in general what the problem is. IMHO this
        should *not* include CATS. Anyone unfamiliar with CATS should be
        able to understand your problem.
 2. Terminology
      * Define any terms not defined in RFC8446bis
 3. Motivation and design rationale
      * I really like how Russ motivates the problem statement in
        RFC8773bis [0]. Use it as a sample.
      * Here you should address all the concerns from WG, including
        justification with compelling arguments and authentic references
        why you think it should be done within TLS handshake.
      * You could put CATS here as a motivational use case.
 4. Proposed solution (one or more sections)
      * Protocol design with protocol diagram (Use TLS 1.3 /only/)
 5. Security considerations
     1. Threat model
     2. Desired security goals
     3. Other security implications/considerations

Hope it helps.

You may also find [1] helpful. I will update it in the next weeks with 
more details.
