The soap's recent internet counterpart E20 - which focused on young Walford newcomers Zsa Zsa Carter (Emer Kenny), Leon Small (Sam Attwater), Arthur 'Fatboy' Chubb (Ricky Norwood) and Mercy Olubunmi (Bunmi Mojekwu) - was a hit with fans after it launched online last month.
Asked whether viewers can expect more online spinoffs in an interview with Walford Web, Yorke replied: "We hope so - we're incredibly pleased at how [E20's] gone down - it's harder and harder to reach a young audience every year.
"We're feeding all the characters into the main show so they will certainly still be around, and if we can come up with the right idea then something should happen."
EastEnders' executive producer Diederick Santer last month said that he was "delighted" over strong viewing figures for E20.
The 12 webisodes were created to tie in with EastEnders' 25th anniversary and were penned by young London writers aged between 17 and 22.
