A while back, somebody asked a question that actually contained three related, but fairly distinct subquestions. This question was subsequently closed a few days later on account of being too unfocused, but before I discovered that, I'd already typed up a detailed answer addressing all three of the questions raised, with supporting references. As the question had already been closed, I was unable to post my answer/s.
Would it be reasonable for me to edit that question to remove one or more of the subquestions (and post it/those separately), so that the thread could potentially be reopened, enabling me to answer all the questions raised? Or would that be going too far, in the sense of fundamentally altering the nature of the question?
