Wow, yours is a very specific, unique case. That's not bad at all... Just interesting! You obviously have some stellar leadership experiences in your past, which is typically one area where b-schools will focus on when considering someone with little or no work experience.
The other area that they will focus on is answering the question "Why do you need an MBA now?" You will need to have a tight answer here. Especially think about the "now" part of that question... Why not get your MBA in 3-4 more years? I think you have a good reason and realistic post-school goals, but they will really focus on this, so be ready.

BTW, you probably already know a lot about Wharton, but here is the answer one their web site about work experience. As you can see, they focus on quality more than quantity:
