The actress told Bang Showbiz that she would like her character Rosie Webster to head back to Weatherfield with a baby in a surprise storyline twist.
Flanagan commented: "You can never say never. Who knows what will happen in the future? I love Coronation Street. I was on the show for 12 years and was fortunate enough not to be killed off on the show, so there's always a chance of going back."
She continued: "I would like Rosie to come back with a bang. She's been away in London doing modelling so she probably thinks she's a bit above everyone.
"But I'd like to see her back with Jason, or it would be great if she came back with a baby. I'd love that."
Flanagan added that show bosses should also bring back Kevin Kennedy's popular character Curly Watts following recent press speculation.
She said: "It would be great if Curly Watts came back!"
Rosie split from Jason and left Weatherfield in February 2012 after Flanagan decided to bow out from the role.
