"I just threw it out there for something to think about and I'm deadly serious about it," Lewis stressed to a gathered media contingent on Wednesday.
"I know Alan Jones well enough to know that given the opportunity I reckon he'd grab it with both hands and make a success of it."
A press call had been hastily arranged at QRU headquarters after a report on Wednesday quoted Lewis throwing his full support behind Jones for a second spell in charge of the Wallabies.
After succeeding Bob Dwyer, Jones coached Australia to 23 victories in 30 Tests between 1984 and early 1988 and has been praised for his work in reshaping rugby's line-out and back-line play during that successful stint in charge.
"In terms of doing the job as a Wallaby coach I think he is eminently qualified. His record speaks for itself," Lewis said.
"The fact that he stopped coaching doesn't mean he stopped having the ability and I know he's got the passion."
Lewis also maintained Jones' rugby brain was the equal of anyone in Australia and that his teams would bring entertainment back to the national side.
"There was no more exciting and successful team than the Alan Jones team of the mid-80s," he claimed.
The crux of Lewis' backing for the Queensland-born media personality is his capacity to inject a fresh approach into the World Cup quarter-finalists.
Comparing the situation to previous coach Connolly's reappointment in 2006, Lewis questioned whether any of the potential candidates reportedly interested in the Wallabies job would bring a new slant on the game.
"Is any one of them doing anything radically different that's revolutionised the game and is an absolute winning formula? No. That's what this thought is about. Let's do something completely different," he said.
"Age and time expired means nothing. It's who's best for the job."
Lewis insisted money would not be an issue for Jones, suggesting he could take the position on a part-time basis.
"(Jones) isn't interested in money. It's the passion for the game and the opportunity," he said.
"It's certainly not a full-time job in the sense it's a 52-weeks-a-year job. That's crazy.
"If you have to be there 40 hours a week being the Wallabies coach in the middle of January what are you going to do?
"You analyse things so much that you end up killing it. That's part of my issue with this whole thing."
