Hello, please evaluate my chances at some top schools

Age: 28 at matriculation.

GMAT: 780 (49q, 50v) - 2nd attempt, first try a month prior I felt unwell and got a 730 (45q, 45v)

My Achilles heal is my GPA. I have a 3.25 from BYU, studying food science and nutrition. I am taking two additional classes right now - Calculus and Microeconomics, I am on track to get A's in both of them.

WE: Almost 3 years at matriculation for a large ingredient and flavors company doing product development. No direct reports but I've continuously been given higher profile projects to manage as well as bigger clients. I've managed development projects through to production for companies such as McDonalds and OSI, Arby's, Nestle, Tyson etc. Should have excellent recs.

Also I had an internship with Nestle for the last year and half of my undergrad as a quality analyst. I worked in a production plant doing projects for hazard, sensory, and microbiological analysis. Its not formal work experience, but I think its pertinent because together with my current work experience I have a pretty deep understanding of my industry. I worked 20-30 hours per week and also trained incoming interns.

EC: 2 year LDS mission to Central America, fluent in Spanish. According to Whartons website, they also count this as full time work experience.
During college EC's were ok, I was active in a couple clubs, intramural sports, and church service.
After college: also pretty good, various church service positions including current leadership position. I'm also organizing and leading a service project for a hospital in Ghana.

Post MBA: hopefully leverage my project management and problem solving skills to work for a top consulting firm. Eventually I may move into management for a company such as Nestle or General Mills.

What do you think of my chances at:
Wharton
MIT
Chicago
Kellogg
Yale
Texas

Thanks for your help.
