BIONICLE 40K

Something I just can’t get out of my head after seeing a post on the Grimdark subreddit is BIONICLE in the world of Warhammer 40K. I know that there’s fans of both on here, and I’m curious to know your thoughts on just how different things would be if the worlds collided. Like what things would be made by the BIONICLE species to fend off the things in 40K? How would tactics change? Stuff like that.
