Advice for Schools - Engineer

I am going to apply this Fall to several different schools. I have a tentative list but I'm worried I may be overly optimistic about my odds at some of these schools. I'm looking to apply to 5-6 total, no more.

My profile:
-25 year old American male
-Graduated in Industrial Engineering at a large state school
-3.55 undergrad GPA, 3.84 major GPA
-700 GMAT (44Q, 41V) - expect an 8 in IR and a 6 in AWA
-Four years work experience (at matriculation) in an engineering position (my job requirements are diverse
-Moderate extracurriculars (I'm also really into homebrewing)
-No explicit leadership experience in job or extra curriculars (there is no room for promotion within my small department); my roles and responsibilities within my job have increased and evolved over my time here though.
-I'm personable and interview well, that should help me (especially being an engineer)

My short-term goal is to go into management consulting after getting my MBA. I think my industrial engineering background is a natural fit for consulting since it is rooted in profitability, productivity and sustainability; I would sell my engineering background as demonstrating my problem solving capabilities. Ideally I'd try to work for McKinsey, BCG, Bain, etc. - I need to do further research to see who is most friendly towards engineers. I'm hoping to get some international experience in the position as well, particularly in Asia.

I'm not dead-set on consulting, but I'm not sure that general management is appropriate just 4 years work experience...I'd go with the consulting angle for my essays I think.

Long term goal is to transition back into a more traditional management role, I think that consulting would give me a wealth of knowledge and experiences, not to mention a vast network, which should make me marketable. I am interested in entrepreneurship down the road but am not sure in what capacity yet.

Duke and Northwestern are my two most desired schools. I'm applying to Harvard as a big stretch, but I would certainly go if I got in. I had Wharton on the list for the same reason, but I'm worried they are both unrealistic. I was thinking that UNC is a good safety school.

Are there any other schools that seem like good fits for my profile? The only schools I'm set on right now are Fuqua and Kellogg, I'm very open to other suggestions.
