The impressionist planned to resurrect his comedy show The Big Impression following the programme's four-year break from screens.
However, corporation executives are said to be showing little interest in a possible comeback for the series, which also starred Ronni Ancona.
"We'd like to go back to Big Impression if the door was open," McGowan told The Mirror.
"I felt I had taken impressions as far as I could at the time. We'd run out of people to do and it takes a while for new people to come along and that's why I stopped doing impressions. I think the time is right for us to go back to it. But I don't think the BBC feel the same."
McGowan also suggested that the BBC lost faith in his now-axed detective drama Mayo too quickly following its debut in March 2006.
"It was taking its time to find its feet and by the end we knew what we were doing," he explained. "But sadly, decisions are made on the first episode and we definitely didn't hit the ground running.
"But we learnt how to make a very good programme and we were all really surprised and very disappointed that we didn't get another series. It is sad."
