I think you're sadly mistaken with the Sedins. I think they would have benefited from clutch and grab. The Sedins were so good on the boards and being elusive in the dirty areas. They would have dominated with the passing plays they could make.
Also don't think Bure benefits in this new era of hockey. I think his speed is what gave him the edge back then. Barely anyone could skate like that back then, and now there are tons of speedsters. Jenner, Virtanen, McDavid, Larkin, Pettersson,etc...
Kesler would have been a force back then... Also this is assuming they keep their skills and IQ of their peak in the modern era.
NewEra
Hindered: Pettersson, One Scott Stevens away from retirement,
Benefit: Sedins. When they slowed down they lost a lot of space in the new era. That's why their offence fell off a cliff, really. Clutch and grab, they would have made the pass before the guy groping him knew what happened. This would be utter domination circa 2011.
Old Era
Hindered: Bure. Goalies aren't so easy to dangle out of their crease anymore and everyone else is a step quicker, not to mention cherry picking doesn't happen in todays game that often.
Benefit: It's hard to pick a guy from this era who would do better against better competition, but I would have to say Alexander Mogilny. He was just so good, I think he would translate well.
