That's an absurdly high standard for top line winger, there were only about 30 pt per game wingers last year and that's stretching the definition of pt per game to include everyone above .9 pts per game. I'd also take any of those guys you mentioned ahead of the vast majority of 2nd line centers in the league. I mean, who is the average 2nd line center, guys like Stastny, Reinhardt, Trocheck, Horvat, maybe Tavares?
I mean, I guess I'm just arguing semantics here as it's just your arbitrary name for the threshold, but it's really hard to get a feel for what you meant based on the name alone without the added info...
Maybe a better way of looking at it is league wide instead of framing it as lines/pairs since as you say, deployment is dependant on the makeup of the rest of the team;
So, does this line up with what you mean?
Top 60 center
Top 60 D
top 30 W (or would you expand your group to encompass guys like B.Tkachuk, Dubois, Giroux, Petterson, Svechnikov that don't quite meet the high standard of pt per game)
top 30 G
61-120 D, and 61-90 C
31-120 W (perhaps 61-120)
I'd still differ a bit, I think a top 30 winger (assuming you still keep that threshold) carries more value than say the 45th best Dman in the league, I probably also would split goalies into two categories as a top 10 goalie very different from a 11-30 goalie, the former to me is on par with a #1 center, while the later is closer to a 3rd line center.
