It doesn't fit the western Canada rumour, but one thing that's crossed my mind is a somewhat unconventional deadline deal with the likes of Arizona/Anaheim.
Both have two things we need- an oversaturation of picks/prospects over the last 3-4 drafts (and the next couple) - potential rental, rental+1 options. Arizona has dipped into that resource pool to add Durzi already, both those teams could see more value in young NHL players to prevent being all rookies rather than yet another 2nd rounder. Tre's had some time to evaluate the team. Keefe has shown his impatience with certain players.
A Liljgren-Robertson-Reaves combinations sends out up to 3.55 in cap, with 50% retention that's 7m in players that could come back.
It's not massive, but player's like Dumba, Henrique and picks could kill two birds with one stone, address some weakness on the current roster (with re-signable players) and add some draft capital, at the cost of players we're squandering/ might not be high on.
