While this is all correct and I like your thought process, I would add some caveats.
You mention Sweden as a draft tendency, but the last good-looking picks out of Sweden, Jaros and Dahlen, were made while Vaclav Burda was still Director of European scouting. As I mentioned elsewhere, we haven't made a single pick out of Europe in the two drafts since he left. We've hired two new European scouts in the past two years, so I expect some European picks in this draft, i doubt they'll be in the first round.
The rest of the tendencies you mentioned are correct, but for CHL, I wouldn't expect a WHL pick in the first round (you dont have any on your list there anyway, but I just want to put it out there).
Our two Western Canadian scouts right now are George Fargher and Bobby Strumm. Fargher was involved in both the Cowen and Lazar picks, and the rest of his record over the past ten years looks pretty miserable. Bob Lowes, now with Vegas, gets the credit for late picks Stone and Zach Smith.
Bobby Strumm was just hired in 2017 and the only name to his credit so far is Angus Crookshank, who is looking like maybe a gem, so perhaps Strumm will be the one to return credibility to our Western Canadian scouting, but I doubt they use a first rounder there this year. I'd be curious how involved he was on Tychonick and JBD, but I haven't been able to find any information on this.
Dorion's most trusted eyes right now are head scout Trent Mann, Don Boyd and Bob Janecyk, so most likely destinations would be QMJHL, USNTDP, OHL. But also as you mentioned, Dorion doesnt mind turning to junior A leagues for high picks.
