Back to undergraduate for another OCR and better programs?

I know this might sound crazy. I have graduated about two years ago with a high GPA in accounting. I am looking into making a career change at this point.

My undergraduate school has a pretty good financial honor program which has placed a decent amount of people in BB. Would going back to undergraduate school be a good choice to break into FO at this point?
Another chance of OCR and gaining more depth knowledge and major in finance make this option sound appealing to me.

As a lot of great people advised here, going to a top MBA would be a good option. IMO, the opportunity cost is extremely high and there is a great chance that I cant get in a top 10 program. For the one year msf program, without prior expierences, there is little chance landing a full time po jobs.

I can probably finish the finance program within 2 years and get an internship in the summer. Additionally, both the living cost and tuition will be very minimal for me.

Thanks for reading! All suggestions are appreciated!
