OK, time to show just how old I am...
There are indeed Norse in Lustria. It's a nod to the historical Vikings who reached Newfoundland. There has been mention of their Lustrian settlements since the 2nd edition of Warhammer at least (the introductory scenario for 2nd edition, "The Magnificent Sven" was set in Lustria and was a tongue-in-cheek reference to "the magnificent Seven" including Dwarves and Norse and with the Slann as adversaries).
Apart from the factions mentioned by katadder, in Lustria there are Dark Elf and Chaos raiders, Imperial settlers (with even more Dorfs and additional Fling sidekicks, presumably), Tileans and whatnot. Also, there are Slann and Lizardmen in the Southlands, equivalent to Tropical and Equatorial Africa, and they used to play BB with Nehekharans (as the LBR5 says), so it would not be inconceivable to have a Lizardmen/Khemri team-up.
Lizardmen are sworn enemies of Chaos, so even if one takes liberties with the fluff (the old "this is not Warhammer!" saw) mixing both races would be too weird. Amazons+Lizzies+Norse/Slann (in the unlikely case they're ever introduced) would work pretty well.
