It can ideed be done, did it for years. It takes forever, thin, airy buds, tall, ugly, sort of like the OP's photos(sorry), but yeah, it can be done.
Get yourself a few decent wattage CFL bulbs, but make sure it's the true wattage, not the usage watt rating. There are some nice CFL's on the market now, and for small closet grows they do great. Also, get yourself a Y splitter for each socket you have and you easily double your lighting. That girl still has a lot of potential, and if you bombard her with good lighting now, I think you'll be amazed at what will happen. She's old and tall, but that means healthy, strong, and more than mature. Hit her with some good lights for another six weeks or so, and my money says you'll have something to brag about.
