I think this would be a great idea. I am going to see if I have any skill at this myself. I am going to start looking for tutorial videos any recommendations would be great, but I love this concept,
There is lore that turning a gnome into an illithid sometimes messes up and they become gnome sized. I would love to have a tiny illithid companion, or just make the emperor really small. Not sure how to do it but it'd be cute to have a tiny illithid in the party or around camp.
