Business School Vs Bachelors & MBA advice for Wallstreet.

Hey guys i am looking to transfer to University of Michigan By the end of the year and hopefully apply and get in to Ross business school and get my degree in finance. I was wondering if i don't get accepted should i stay at U Mich and major in Economics for my bachelors(with a possible minor in business) and apply for graduate school to get a MBA in finance. If getting my Economics degree doesn't sound like a good idea should i consider maybe applying to Michigan State University or University of Michigan-Dearborn and go to either business school or stay at University of Michigan-Ann Arbor to do my bachelors in Economics with a MBA(if i get in) in finance. If you guys have any other ideas such as certain majors and minor to do, or any suggestions with schools i will appreciate it. Thank You
