IIRC, some people have tried using a mesh basket for this and the basket prevents a proper boil, it just kinda burps up around the outside of the basket. However, I believe these baskets were sized so there was minimal clearance to the kettle sidewall and they were made from 300u/400u material.
I don't think anyone has reported trying it with a COFI per se. Since the COFI is a bit smaller in diameter than the kettle and there is a good 1 1/2" clearance all around and as far as I know it is made from 800u material it might have shot.
