I agree. The worst they can say is, "no," and chances are more likely that they'll either say "yes" or "we need more info."
All you lose by trying is the time it takes to fill out the application. (Not that that's nothing! It's one honking big form!)
A word of advice that helped me as we went through the process: remember as you fill out the form that your stories should demonstrate not only that your child is GT, but that he is HG+ and not "merely" MG. Try to choose those stories which illustrate that your child is operating 3+ years above grade level.
And best wishes to your application!
