Liz was at one point intended to have a greater role in the main storyline, though personally I'm not yet convinced that Jay's role was originally her's.
I remember at the time, my autistic headcanon was that she was secretly one of the "cousins" that Hedge was looking for because her name seems to follow the same conventions that his and Guinness has if she was secretly a reptile shapeshifter.
