from what i've read, changing careers out of a part time gig is going to be extremely tough, especially given your age. i'd try to focus on one of the other 2 concentrations.
out of curiosity, what part of finance were you hoping to break into? i'd imagine with your expertise, adding an MBA would make you a good bet for a consulting gig as opposed to a finance one. in that case, maybe the strategic management concentration might make more sense. just my thoughts though
