Thanks, everyone, for the feedback. Still haven't heard from the remaining programs, but had an interesting development that might offer me funding to fill out my academic deficiencies and work on a few publications. Not a ranked university in my field, but if it pans out, i would have a chance to take a few research, math and econometrics classes while working with one professor on a book (thank the powers that be for stumbling into a B.A. in English.) I would also have the option to work on other research papers, at least one of which might give me a lead author credit. This would flush out my CV in its weaker areas, beef up the math section of my transcripts, and find a few more highly targeted recommenders. I'm not certain whether I could do it as a non-degree student, or whether I might have to go the master's route to justify funding by the school. I have to believe that two years hence schools will recognize that academically-minded neophytes had to make certain compromises to stay in the game through these lean years and view positively someone who persevered and kept pushing toward that goal.
