Yes, there are many precedents - Simon and Garfunkel, Daryl Hall & John Oates, DJ Jazzy Jeff & The Fresh Prince, etc. There are even forum threads discussing some of these, so I don’t expect the recrediting to be controversial.
It’s easy to think “this is obvious” and put in some sort of minimal edit note, so I was looking for perspective on what might not be as obvious as I think (like @freso’s suggestion in the other thread of referencing the generating software when adding disc ids).
I wonder if it might be worth adding something to the guidelines regarding duos, for instance formalizing some of the points raised in the Jazzy Jeff/Fresh Prince thread.
