You have a decent profile. Your profile and GMAT Score are good enough to get you admitted into Kellogg and Chicago booth weekend MBA program. The only roadblock in your profile is number of work experience. You can apply to Chicago booth as the average work experience for Chicago booth weekend MBA program is 5-6 years. But, Kellogg has 6 years of average work experience so if you are planning to apply for 2015 intake I think even that should not be even a problem.
However, I would suggest you to write to admissions committee of Kellogg mentioning your number of work experience.
