Under the AFL’s new supplemental selection period rules, clubs would have until March 15 to add him to their list.
In 2018 ,the Kangaroos 400-gamer kicked 61 goals in 17 games for North Heidelberg in the Northern Football League.
Harvey won the clubs best and fairest, becoming North Heidelberg’s oldest club champion at the age of 40.
Cornes suggested Hawthorn as a possible destination for Boomer.
“Clarko (Alastair Clarkson) is the most innovative coach in the competition,” Cornes told SEN’s The Captains Run.
“Would a sneaky phone call to Boomer Harvey be worthwhile?
“It may be a playing and coaching role, playing 12 to 15 games or maybe all of them in the forward line.
“Clearly he can still cope with the rigours of playing AFL.
“If he’s not in the best 800 footballers in the country, I’d be shocked. I reckon he’s still in the best 400.”
Cornes believes that more clubs than just Hawthorn could benefit from Harvey’s services.
“I know it’s a long shot to try and convince him out of retirement, but try and convince him in different ways,” he said.
“With the new rules, why wouldn’t a club sign him? Is he in Carlton’s best 22? Yes.
“He’s probably in Hawthorn’s best 22.”
