At my college they offered aBA in straight up liberal arts. I knew a guy who declared it as his major and he said there were two or three other people who were also pursuing a degree in liberal arts. He was interested in economics and was in a few of my more interesting economic classes. He had to concentrate on a handful of disaplines of his choice. See if it's an option for you?
I'd strongly advise against it. Liberal Arts is literally a non-major. It's worse than worthless. Most employers will see that on your resumé and make an immediate judgement, that you not only know nothing in the field they're hiring, but you can't make decisions, make bad decisions, are stupid, and countless other bad implications, regardless whether they're true. Get an English degree before Liberal Arts. At worst, English is worthless. Liberal Arts can be actively harmful.
