1st Year Ops. Analyst and Pursuing an MBA?

I've been a WSO lurker for sometime, but this is my first post, so allow me to give you some background information. I'm currently a senior, finishing up my last UG semester at a non-target school. Despite the 'non-target' designation, I secured an offer from a BB institution in operations. Working in finance has been a dream of mine for some time, as I'm sure like you, the Street fascinates me. My question stems from my love of academia, and a commitment to achieving an even higher education.

From reading as many posts on here as I could, I've gathered that operations isn't AS intensive as other areas of the firm, and I may actually be able to have a life outside of work. Great! But what better way to spend some of that free time than to work part-time on an MBA? I could easily get into a private, regional institution with a reputation of providing a quality education (ACBSP accredited). Granted, a prestigious Wharton/Harvard/Yale MBA it is not - but does it really matter in the grand scheme of things?

My train of thought goes like this... By the end of my two year program I will have analyst experience at a large BB (think MS, Citi, JPM), in addition to an MBA! It may not be easy, but I'm used to working and going to school full-time.

What are your thoughts? Achievable? Ridiculous? Brilliant? Stupid? I'm new to the Street, so any and all advice would be much appreciated.

Thanks!
