The BBC drama went live earlier this year to celebrate its 25th anniversary. The dramatic episode, written by Ashdown, saw Stacey Branning reveal that she was Archie Mitchell's killer - moments after the death of her husband Bradley.
Speaking to Walford Web, the writer admitted that he knows what he wants to happen in the episode, should it get the go-ahead from executive producer Bryan Kirkwood.
"I have an idea for one," he said. "But it’s very, very different in style. All I’ve got to do is persuade Bryan [Kirkwood].
Discussing the challenges surrounding a live episode, Ashdown commented: "Firstly it had to be a good episode in it’s own right: good structure, good story, some truthful emotion and high impact moments."
Ashdown has penned Stacey's upcoming Christmas Day exit from Albert Square.
