Hello there!
Well you certainly have a very interesting and unique profile, and I think that coupled with a great GMAT and very good grades should make one of the S16 possible (although you still may want to have one or two schools outside the S16 on your list, as safe schools).

Basically, I think that with your news involvement, you really have the potential to write a fascinating application.

Since you are not from a business background however, it will be very important that you show WHY you want to go to Bschool, how it makes sense, and how these fit into your goals. Basically your career story is gonna be one of the most important factors in your application.

Next: I wouldn't worry about the AWA tooo much. Just write beautiful essays.

As for the LGBT, I don't know that it will increase your chances, but if it's important to you, and you have something interesting to write about it (of course relevant to the application and the questions asked) it can give a new facet of your being, which you may want to present.

Best,
JF
