Interesting Idea but I have doubts that it will work well. I hate to be pessimistic but to me it just sounds like your are going to select a few people to come up with a very few amount of questions with a limit them on the subjects and then just maybe answer those questions, maybe. It is a way of avoiding all the other questions that are already being asked. Plus you leave yourself a loophole saying that it is all subject to change do to development constraints which just employs that encase the question asked is something that you do not want to answer then you have a way and reason to not answer it.
I think there will be a lot of questions suggested that you all can not get into. So I really see this going no where.
That is just what I see this as becoming.
