Don't see Steen being dealt--and if he were, he wouldn't be waiving trade protections to go to the Isles, who aren't exactly hurting for LWs. Speaking of which, the Isles are in desperate need of LD--I'd be looking to move Gunnarsson to them (I've advocated packaging two of Gunnarsson, Walman or Schmaltz to the Isles for Mayfield, just to have an experienced crease clearer as 7D).
I'm excited about Reinke (kid has hands the size of Andre the Giant), but I don't think he's quite ready, and shouldn't be playing ahead of a healthy Bortuzzo. And hanging on to Walman likely means he suffers the same fate as Schmaltz--buried by depth, lost value, squandered potential.

If we did somehow move Steen, I don't see how we don't replace him with Kyrou, unless there's another worthy winger coming back in the deal (Steen+Kostin for Skinner? Doubt they'd do it, but I would).

In any event, it will be interesting to see how this roster turns out. Yeo certainly has lots of possibilities to work with! I just hope they don't allow salary considerations to dictate roster positions--we should be dressing the team that gives us the best opportunity to win, every night, period.
