I think you're going a bit far and overrating several of those riders but I'd say they could be average. And of course, teams that try to keep their rosters local pretty much never get anywhere near all the top riders from their country so more realistically you're looking at a team that would be closer to a bottom tier WT team.Obviously it is easier to be able to pick riders from all over the world, but saying a Norwegian/Danish squad can't work is far from the truth.
I mean, the top 20 on the list is:
Fuglsang, Asgreen, Mads P., Kragh, Vingegaard, Kristoff, Honore, Foss, Hoelgaard, Tiller, Cort, Halvorsen, Kron, Valgren, Casper P., Leknessund, Moerkoev, Wurtz, Bystroem, Skjelmose.
With another 5-10 Doms to complete it, that would be one of the strongest teams on the WT.
