I've always loved the idea of Weird West. I don't know if there is a widely accepted "definition" of Weird West but for me it's almost anything that breaks the Wild West tropes or setting in any fantastical/absurd way. All of this to say I would put this in the Weird West category in my own personal interpretation.
TLDR: In my personal opinion, any significant addition of scifi/fantasy/absurdist things to break the Wild West mold is Weird West. So yes, I see it as Weird West.
