Swan said Cousins had been his favourite player and a "freak of an athlete" who could help boost the Collingwood midfield.
“Definitely. You know, he’s a champion. But as long as, I think if he got cleared from everything he had to do, I don’t know what has to happen for him to play AFL.
"But if all that went through, I’d love him, I’d love to play footy with Ben Cousins.
“He was my favourite player, favourite midfielder the way, how hard he worked,” Swan said.
Swan, who finished sixth in last year’s Brownlow medal, said the 2005 medallist could lift the Magpies.
“If he can come and just play a good two or three seasons with us, he’d just give our midfield so much more dynamic structure and, you know, he could take us to the next level.”
The link between Cousins and the Magpies is strong as Mick Malthouse coached him for his first four AFL seasons at West Coast.
Former Eagle Karl Langdon last month said Collingwood was the most likely destination for Cousins if he returned to football.
Last week it was revealed St Kilda had spoken to Cousins about the possibility of moving to Moorabbin.
For Cousins to be eligible for selection, the AFL must grant him medical clearance to resume his career – which will only happen if he could prove he had overcome his drug addiction.
Cousins would then have to nominate for either the national draft in November or the pre-season draft for uncontracted and delisted players in December.
