The actress said that she wants Katy to play a more prominent role on the cobbles as she continues to grow up in Weatherfield.
Foote told the Daily Star of future storylines: "I would love one like Alison King's. She's been brilliant. Something to get my teeth into would be good, and maybe a bit more glamorous, too.
"And I would love Katy to have a job behind the bar in The Rovers. I've worked in a bar so I love that sort of atmosphere and the banter you get from the customers. She's a bit young at the moment, so maybe just collecting glasses.
"The Rovers Return is gossip central. Everything seems to culminate there. I would really like to be in the thick of the action."
16-year-old Katy welcomed the arrival of a baby boy named Joseph at Christmas, but struggled to cope with her new responsibilities in the first few weeks of this year.
Foote commented: "The post-natal depression storyline has been hard and I found the filming very intense. It was quite good because it only ran over a couple of weeks, but I did end up locking myself away until I went on set.
"The Corrie green room is so lively, so if I was to go in there before a scene I couldn't switch to being sad and crying my eyes out on set. I would hide away until the last minute. Post-natal depression happens to so many people, so the pressure to get it right was huge.
"I was going home after a day's filming and feeling really tired and with a headache from the stress of it all. I can't imagine how hard it must be in real life."
Coronation Street airs Mondays, Thursdays and Fridays on ITV1.
