The Wings' front office will be interested in neither Liles nor Komisarek. The Wings have five offensive defensemen playing nightly already, making Liles completely unnecessary; and as Komisarek is an underperforming, hugely overpaid defenseman with a year still left on his contract, there's not a chance that they'll touch him either. For that matter, no team that is interested in being competitive will make a play for Komisarek; the impending decrease in the salary cap would ensure that even if his inadequate play hadn't done so already.
As other have noted, if he's moved he'll probably be heading to a cap floor team, and---assuming that he isn't the Leafs' amnesty buyout (which would be a tacit admission that Nonis might not be able to move him at all---it'll happen in the offseason. Every team is above the floor for this season already.
As I noted, there's not the faintest chance of this happening. More, what you've said is incorrect. The Wings do not need another defenseman---they currently have eight who are capable, and the defense has really begun to gel over the past few games---and though the Wings have indeed have a lot of success at reclaiming players who have fallen upon tough times, never are those players who are on large contracts. Picking up a down-and-out player and giving him league minimum is a risk only in the most minimal sense. Taking on a guy who'll be a salary cap liability if he doesn't perform is an entirely different story.
Further, how many Leafs defensemen have actually moved directly from that team to the Wings over the past decade? I can't remember any. There certainly haven't been any since Larry Murphy who have moved on to the Wings and retired as a member. For that matter, there have been very few ex-Leafs defensemen on the Wings at all during that period. And for those on the team right now Detroit is very unlikely to be the final destination. White is unlikely to get another contract with the team after this season, and Carlo will likely spend his days with the Wings as a depth defenseman; barring a tremendous resurgence, he's likely to be on the way out after his contract ends too.
His giant contract plus the shrinking of the salary cap plus the incapacity under the new CBA for teams to stash bad contracts in the minors equals many reasons for competitive teams to stay away.
