I have, in my own biased opinion, an amazing and beautiful answer that was given to a question that was changed so that the answer was eventually made irrelevant. For the original question, in my personal opinion, it was an excellent answer.
Is it inappropriate to make a new question, based on an earlier version of the original question, and supply my answer as an answer?
I really think the answer was a thing of beauty and I put some good time and thought into it. I have received quite a few up-votes on much simpler answers to the same general topic and I feel that this answer would be valuable to the same audience. I think that given the nature of the current question, that the answer will never "see light of day" or be found and accessible.
UPDATE: (request for clarification)
If I am going to ask the question, then answer it, how long is a reasonable time to wait for others to answer? I am committed that if someone else has a reasonable answer to select theirs as best before putting my own answer "into the ring".
