I am not swede myself, but I could try and find a swede/dane volunteer to help with battlecries, need to ask some people. I'll message you of course if my search succeeds.
And yes, I noticed scandinavians as part of crusader faction, which is not very accurate historical-wise. While the danes were more like continental nation who had very strong connections with their neighbours germans and took part in some campaigns (like the Livonian Crusade), and hence could be affiliated to "crusaders", swedes were different.
First of all, they weren't feudal state in common european sense. Second, they didn't share "missionary" goals with european kingdoms who were heavily dependant on popes and their will. Third, they didn't participate in any "official" crusades.
In fact, what is sometimes called "swedish crusades" was nothing more but seizing control over Finland (disregarding of any religious motivation) with consequent border/sea skirmishes with russians, who also had their interests there. Thus their finnish expeditions and attempts to establish an outpost in estonian lands were claims for regional power, their fights with Rus (and particulary novgorodians) had deeper roots. Ever since viking times, when the river route to Black and Caspian seas was found, there was rivalry for trade control. Vikings came to rule slavs, slavs assimilated vikings, swedes raided rus, rus raided swedes, and even lands changed owners again and again.
That's why I believe that placing swedes into crusader faction is historical mistake, while not introducing them to the mod is actual mistake. It's like making game about Great Patriotic War without North Front and Leningrad. Everyone knows it should be somewhere around, but it just is not present. Uncomfortable feeling of puzzle's missing fragment, if you understand what I mean.
And talking about "lot of game factions", I always thought that more factions add more color and challenge to the game, not vice versa. In case of Poland which is quite compact (in game) and hardly dividable I must agree, but Rus is very stretched and covers really large and empty territories. Would it really hurt game balance if making two factions out of it (considering you don't need to do a lot of additional artwork etc)? Same with swedes who could use a lot of fancy items/models from warband (and native too). But I'm afraid it's too late to talk about it on current stage of mod production...
