Carbon fiber composites are not new materials, although being a bit novel to the aircraft world. There are plenty of repair technology documentations.
The materials used in the Comet 1 were not 'novel' in themselves. With a 200 tonne+ heavy jet flying at near the speed of sound, with 15 psi internal pressure, for fifteen hours a day in turbulence, taking off and landing, the airframe is in a very severe environment, hard to replicate in the laboratory. Forces, changes in force magnitude and direction, vibration, temperature and chemical/moisture attack are hard to replicate in any faithful manner together as a complete structure. With a new aircraft, tens of thousands of hours are flown in real conditions long before the a/c enters service.

Yes, a paper would be most interesting but I venture a guess that that won't happen. Sadly, because this is a very interesting case due to the placement of the damaged area.
I don't think that 'most interesting' is the appropriate term. It is vital that the proposals are peer reviewed by a range of materials and aviation specialists if the repair is going to be tested on the public (or line flight crew, come to that).
