Speaking of the Leafs, it would make sense for them to consider Dubois as a 2C, if the cost of acquisition is reasonable - and it should be. It's very public news that he wants out of Winnipeg, and he is, as mentioned above, only a year away from becoming an unrestricted free agent, which means the cost should be low. He's a nasty, big-bodied pivot who displays a great level of skill as well. Here's a clip from one of the Leafs vs. Jets matchups during the 2021-2022 season:
Ultimately, even if the Leafs were to bring in Dubois knowing that he'd only be in Toronto for one season, it would be an excellent fit for the Buds, who are looking to change the identity of the team a bit and get away from being viewed as "the Core 4 plus 19 other guys".
