Einhyr Hearthguard - Alternative Heads

Hello Kin! I’m half way through assembling my Einhyr Hearthguard, and I’ve been struck with inspiration. I want to style my Hearthguard as Valkyries, to match Grimnyr’s Odin vibes. I have most of the female Kin heads picked out, but I’m not too impressed.

Would anyone have any suggestions as to good alternative or proxy heads I could use? I know the proportions for Imperial Guard heads would be off, from other posts.

Thank you for your time!
