Lyon has been linked to the Blues job despite being contracted at Fremantle until the end of 2020.
Cornes says Lyon is exactly the type of mentor Carlton’s young list needs, and the Dockers could be better off moving in another direction.
However, he was unsure if Blues fans would embrace Lyon.
“I’d love to know how Carlton fans feel about that. What would the reaction be if Ross Lyon came to the club?” Cornes told SEN’s Crunch Time.
“I think that is probably a win-win-win. A win for Ross, a win for Carlton, I think he’d do a good job there with a young list, and I think Fremantle would be happy to give him their blessing to go to another club and move on, so it could work for all parties.
“I’m just not sure whether Carlton fans think he’s their man.”
Cornes thinks the final six weeks of the home and away season could dictate Lyon’s future at Fremantle.
“If it turns ugly in the last six weeks, I don’t think it’s unrealistic that they might part ways with Ross and they’ll go in with a new coach, I don’t think that is out of the question,” he said.
“I think it’s a big six weeks for Fremantle to be honest. I’ve been so disappointed in their last four weeks, they’ve been the most disappointing side in the last month of anyone bar Gold Coast.
“I think he’ll remain coaching there if I had to put money on it.”
