its a great idea. Regarding the Q&A, I would propose that whenever a topic has been chosen by Mufti saheb, a sticky thread is created on SF one or two weeks before, so that all members can post their questions in there. Thereafter, some moderator can sift through it and prepare a list of questions which is given to Mufti saheb beforehand. This process will have the benefit of having clear and concise questions to be answered, irrelevant ones will be discarded, and duplication will not occur, among others. And due to the fact that the questions are known beforehand, it will speed up the Q&A session and more time will be available for Mufti Saheb to deal with each and every question, and go in much details if required. In my weak opinion this should be the ideal way of going forward.
