When creating a custom space marine chapter i wanted to make something that was a little unique visually. Right now it doesn't really have anything that stands out so I decided to add a fast attack/cavalry like unit to add to my chapters knight like appearance.
I searched through existing Warhammer 40k mounts and found non that fit within my price range since they were pretty costly and the ones that weren't costly weren't what I was looking for visually.
I then broadened my search to the age of sigmar collection and found the vanguard-palladors.
What I wanted to know is, could a space marine fit on top of a gryph-charger from this set? And if so, would it be acceptable lore and game wise. (If I used them I would use the attack bike datasheet)
