The actress played the role of Lisa Hunter on the Channel 4 show from 2001 to 2005 and was also seen in late-night spinoffs Let Loose and In The City.
In an interview with Take 5, Atkinson confirmed that she is now keen to reprise her part as Lisa, even though she is unsure of how the comeback would work.
She explained: "I've not been asked to, but I'd love to go back for a few episodes.
"In the show, one brother has died, my sister is in France and the older brother is now in Emmerdale, so I don't know how they would introduce Lisa back."
Atkinson is currently appearing in a touring production of Calendar Girls which also stars Hannah Waterman, Letitia Dean and Lynda Bellingham.
