Birds of a Feather ran for nine series between 1989 and 1998, regularly pulling in big ratings for BBC One.
The show starred Pauline Quirke and Linda Robson as sisters Sharon Theodopolopodos and Tracey Stubbs, who move in together in Chigwell after their husbands are convicted of armed robbery. Joseph played next-door neighbour Dorien Green, who was notorious for her affairs with younger men.
Joseph, Quirke and Robson have been on tour with the show this year and the audience response has sparked rumours of a possible TV comeback.
"They are in talks to bring back the television show, with the three of us, as it wouldn't work with anybody else and I'd absolutely love to do it," Joseph told The Mirror.
"Pauline, Linda and I have loved the stage show. It's a very unique bond that we have and it has been simply glorious to be a part of, it really has. We've had a fantastic time.
"We have packed out every night on the road and most evenings we've been getting a standing ovation. It's like we've never been away."
The TV show and theatre tour were both created and written by Laurence Marks and Maurice Gran.
Pauline Quirke claimed earlier this year that the BBC had yet to approach them with any sort of offer of a reunion.
