a question about the skrall

good day to you greg, i would like to ask: were the skrall inspired by the orks from the warhammer fantasy and 40k universes? their hierarchy is kind of similiar:
(i am comparing them to the 40k orks because i understand those more)
attakus-ork boy
stronius-ork nob
skrall (glatorian)-ork nob
also the fact that their weapons are made of scrap and bones (even though that is a thing for the entire population of bara magna), their savage nature and slightly orky faces.
so basically, the resemblance is there and i would like to ask if it was deliberate.
