My thought would be we could use a bit of focus on the clanners during some down time to flesh out their personalities and friendships a bit more. clanners in general seem rather standoffish sure. but we have talk of the ghost bears liking football and other such things as well.
Probably would have gone for the A, D, or Prime. that said N is a long range beast. probably runs too hot though so it would need some alterations. still running dual ERPPCs to keep the warrhammer feel. respect.
even just clan Ferro is a fair upgrade if you just up armor the warhammer with the saved tonnage. clan tech 70 ton warhammer isn't quite gonna be a warhammer IIC but you can get pretty close.
