My question was closed as not constructive, despite having some pretty decent answers. After some thought I can more or less see what was wrong with it, and I'd like to make it into something useful. Is it okay if I edit it completely, slightly altering it's meaning, if the answers given will still be relevant to the topic?
This is really three questions:
Is it acceptable to edit a question that got closed before any answers were accumulated?
Is it acceptable to edit a question with a bunch of answers on it in such a way that slightly alters its meaning?
Is it acceptable to edit a question with a bunch of answers on it, in such a way that changes its meaning substantially?
Interesting question. I was fairly heavily involved in your original question, both in answering it (to try to demonstrate that the entire question was founded on incorrect data) and I then voted to close it (since it increasingly seemed to be unanswerable once the error was removed). I'm not sure how you could "heavily edit" that question without making the answers irrelevant, and my guess is that it's unlikely the old question will get re-opened, so no new information will be posted as a result of your edit. My take is, if you think you have a better question to put to us, why not start a new question (though please do read the FAQ first!)?

So if you decide to ignore me and go back and completely overhaul the original question, then whilst I think that's not as helpful as posting a good new question, I don't think I can say it's wrong.
