"I think he'd be best in the back pocket," Longmire said ahead of their clash with the Suns on Saturday.
"I think that's where his best football should be played.
"But I'm pretty certain 'Bluey' (McKenna) won't do that."
On a more serious note, Ablett looms as the major stumbling block to the Swans after the Brownlow medallist's starring role against St Kilda last week had experts comparing him with the best to ever play the game.
Longmire knows he needs to have a number of options up his sleeve if he is to counter the influence of the Gold Coast captain.
He admitted to AFL.com.au recently that the Swans had erred in the past by not making a switch, allowing Ablett to take control of a match in a five-minute stretch.
But he is backing his players to do a collective job on the Suns' superstar.
"We've got a few options. Obviously (Jarrad) McVeigh, (Kieren) Jack, (Ben) McGlynn, those players that have played those particular roles in the past are chances to play on him," he said.
"Sometimes you have to go to different options at different parts of the game.
"A bit depends on whether he plays forward or midfield.
"That's the challenge of playing on one of the best players in the game. He's a star. He's an absolute star. Many say he's one of, if not the best, player to play the game.
"But we have some players that we think are really good AFL players that are making their mark as well and that's a challenge for them."
Longmire said Adam Goodes suffered a knock to his knee in the 30-point win over GWS and he took very little part in training on Tuesday, but he should be fine for Saturday afternoon.
Premiership players Craig Bird and Mitch Morton, along with Andrejs Everitt and Jed Lamb, performed well in the reserves and are pushing for selection in the coming weeks.
The Swans will be heavy favourites to record a second consecutive win, but Longmire remains wary of a Gold Coast side with big ambitions.
"They've said it themselves, they think that they're a real chance to be successful very quickly," Longmire said in reference to Gold Coast chairman John Witheriff's bold plan to win a flag within three years.
"We understand that they'll be confident coming down here, coming off what the coach said was the best win they'd ever had."
The Swans will also unfurl their 2012 premiership flag at the game and they will be hoping for a better outcome than in 2006, when the 2005 flag was raised ahead of a disappointing loss to Port Adelaide.
"It's a thank you to a lot of people, most importantly our supporters," Longmire said.
"We have to get the mix right of understanding that as soon as we've done that, we've got the Gold Coast in about 20 minutes' time.
"That's our focus, but it's an important statement for the club to be able to officially sign off on that and thank everyone involved."
