I need some serious advice ...

What are my chances and what is the best route to take...

While my post count is zero, I have frequented these forums for roughly 2 years. Unfortunately, my situation is somewhat difficult to wrap into the standardized box. Because of this, I am looking for some stern, straightforward advice. Here is my situation (Forgive me for the lack of details, I wish to remain completely anonymous)

Background

Sex: Male
Age: ~27-32
Major: Jr. Accounting (Its a top program without revealing too much info)
Projected Graduation GPA: ~3.7
Projected Graduation Date: 2012 (with Masters?)
Prior Major: Comp Science
School: non-target (investment banking), huge target for Big 4 accounting firms
Experience: 7 years Sales Floor management high pressure real estate investment programs, (home-based biz opps.)
Personality: Sharp, confident, outgoing, witty, people-person, determined, perhaps overbearing
Work Hours: ~45 hours/week
School Hours: ~40 hours/week

Questions:

Assuming the personal stats listed above, a desire to work 80+ hours a week, a desire for job placement in a high-paying, high-stress, quantitative/client based job field, what industry should I be looking to break into? (I want to work more than 80 hours a week, I hate sitting around with my thumb up my ass, I don't plan on having a family, I like to compete more than a normal human should)

While I understand I might have picked the wrong major, (I have very little knowledge of how accountant's lifestyles pan out, but I do know they seem competition-less, and introverted) what should I be trying to do after I graduate with a BS in accounting? With the information from my first questions, would it make sense to get a MACC? If this does not make sense, what things must I do?

I have outlined options for myself (tell me if they make sense):

1. double major with economics, get a MACC, work for Big 4, cross figures for exit opportunity to my ideal career
2. graduate with BS in accounting, find mediocre job, study 20-30 hours a week for GMAT, ace it, then app. to top tiered MBA program
3. double major with math or comp sci, get a MACC, work in financial industry, while working study for GMAT, pass GMAT with high scores, app to high-ranked MBA program

Possible Barriers:

1. Duly noted, my age will create some possible unwanted consequences; I am bright enough to understand that employers succumb to unspoken discrimination. Fortunately, I have good family genes and I plan to work until I am 80 or older,

2. I am a bigger gentleman, no not fat. I am weigh 275, 6'1" suit size 58, waist 38" brown hair-blue eyed, darker skin. Most people think I appear to be a high-class, European, hit-man. I post this out of seriousness as I have had a difficult time creating rapport with visiting recruiters, professors, bosses, and professionals; i.e., minimal eye contact, trembling demeanor when I speak to them (the nasty feminist recruiters become defensive without reason). While some may consider this an asset, for me in the accounting world, these physical traits, thus far, seem to have destroyed me.

So, with this limited information, where do I go from here? If at all possible, serious suggestions, answers, and evaluations would be appreciated.
