I don't think Hoglander would be anything more than the secondary piece in a potential Guentzel trade, especially in a Guentzel sign and trade.
After thinking about it, what I'd be shooting for is Mikheyev, Lekkerimaki and Raty for Guentzel with an extension. The Canucks keep all of their future picks plus don't pull much off of the NHL roster, but the Penguins still get a great prospect in Lekkerimaki and a good prospect in Raty. If you consider the #17 pick in 2023 and Lekkerimaki to basically be a wash, that deal ends up being Horvat and Mikheyev for Guentzel and Beauvillier.
