People say this, but there's still intensity in those games. Especially with guys like Landy, Dutchy, and Varly growing up Av fans, and McLeod who threw their octopus out of the rink a few years ago. Everyone gets up for those games, the Wings have just had by far the better team for a while now so the games aren't close.
As soon as the Avs started to get competitive, those would have be some of the better games of the season. Not like the old days, but still better than others if they weren't to move out of the conference. Especially if they were to meet in the playoffs again, with the Avs gritty team makeup.
It's really not hard to start a rivalry going. The Canucks, Hawks had a rivalry for a while because they met each other in the postseason 3 years in a row.
While it might not be the same as the Red Wings, I don't think that rivalry would ever reach it's peak again. By the time the Avs are truly contenders, the Wings will be a bubble playoff team imo.
