looking for Vashtorr a house name and opinion on scheme idea

Hi there, as the tittle said, i was thinking about making my CK army into a house name aligned with Vashtorr.

Also i was wondering if using Vashtorr-like and maybe iron warriors colors as the armor colors would work? I tried looking around but can't find anything and i am a bit scared of commiting to it and having it looking fugly.

I was planning on doing some green stuff work to integrate flesh and other mechanical tubings. But i am just scared of screwing it up royally
