Personally, I wouldn't do it. Kaiden Guhle plays big minutes against the best opponents and has been doing so since the start of his career.
While he may not be the most productive offensively, he's more than capable of joining the attack. His defensive side is superb, and the rest can only improve.
The goal of doing this is certainly to secure the services of Ivan Demidov, who promises to be a very special forward, possibly the most talented for the Canadiens in decades.
However, what's the point of strengthening one position while weakening another? It makes no sense.
Guhle has his place with the Canadiens, and the team needs him. He's a product of the Habs, and he loves playing in Montreal. He'll be very good for a long time.
