The actor-turned-documentary mentor made his name as Grant Mitchell in the BBC One soap before leaving in 1999. He briefly returned from 2005 until 2006 and again this year for Dame Barbara Windsor's exit as Peggy.
And speaking on ITV's This Morning on Wednesday (21 September), he said another return hadn't been ruled out.
"Yeah of course I would [return], yeah, why not. If I got the opportunity to make documentaries and to act, why not do both?" he said.
"I loved going back. They say a change is as good as a break and one moment I was in Mongolia going down a coal mine meeting Nazis and then three days later I was in the dressing room at Elstree," he added.
"I was quite nervous going back actually, there was a bit more expectation. When I first started, when I was 25 years old, a long time ago, no expectation. Now, you've hopefully got something to live up to."
He returned to Albert Square for Grant's mum Peggy's emotional exit: her character had been suffering from cancer and opted to end her own life through a cocktail of tablets.
It gave fans a final chance to see the Mitchell brothers - Grant and Phil - with their beloved mum Peggy, one of the show's most iconic characters.
At the time, Ross said: "When I was approached about returning to EastEnders for Barbara's final episodes, it was something I could not turn down. Barbara is a very close friend, so when I learned of the storyline it felt right that the Mitchell brothers are reunited with their mother for the last time."
Ross is currently promoting his new documentary series Extreme World.
