Vanessas Low Game

For the most part I've noticed Vanessas low game is pretty weak but I'm looking for more ways to lure out a duck from my opponent. I'd prefer not to eat a low punch counter by overextending myself high.
Her is absolutely horrible except for possibly spacing and her bread and butter low kick and sweep don't give very good frame. I use her from MT fairly often to keep some low pressure on but it doesnt yield much advantage, and most of the time I keep in DS anyways.
Am I stuck paying a standing game with Vane and relying on as my pacing tool (damn Vane and her sluggish jabs)? I'm doing OK mixing up her standing game and throws but I'm keen to expand my low game with her and hopefully draw out some ducking.
