Laidley said attempting to play all key talls/forwards David Hale, Corey Jones, Aaron Edwards, Hamish McIntosh, Drew Petrie and Leigh Brown in the same side was unlikely.
"You wouldn't think that they could all play in the same side, so we'll sit down and have a look at it this afternoon and over the next day or so and come to a conclusion," Laidley said from Foxtel's Melbourne Studios on Monday.
Edwards played his first AFL match since round six – when the Roos drew with the Swans at Telstra Dome – in round 22, having missed much of the season with a broken leg. Laidley said the high-leaping forward showed some encouraging signs against Port Adelaide despite the team's disappointing performance.
"I thought his conditioning was really good. He played nearly 80 per cent of the game, and that's a credit to him to come back like that after three games in the VFL," Laidley said.
"I thought his timing was out, particularly in the first half, but then I thought the further the game went, the better he looked."
"That's one thing he does do; he offers you an x-factor. He can lead-up and hit-up very well, but he can also work back to goal and stand on your head," he said.
"That's where we want a player like Aaron Edwards or David Hale for that fact – we want to have a free run at the footy."
Laidley said Leigh Harding, who has had a fine season in the backline after returning from a knee injury last year, is in some doubt for the clash with the Swans after injuring his knee against Port Adelaide on Saturday.
"He'll have a test later in the week. He'd be probably 50/50, I would've thought," Laidley said.
Laidley said youngsters Gavin Urquhart and Lindsay Thomas will also have their positions in the side scrutinised, but added that it would be "real tragedy" if they were omitted.
"They've done the work to actually get there and it probably happened to Lindsay last year, when he played about a dozen games but really tapered off towards the end of the year," Laidley said.
"This year, his (Thomas) workload has increased and he's played every game – he's played about 80 per cent and he's been a very, very important cog to us.
"It's something we need to have a look at – we can't push it aside - and then we'll make sure we pick the best side to take on the Swannies."
