They were name after egyptian gods?! what i'm a massive fan of both egyptian mythology and HxH but i didn't know they were name after them :O big shock! lol

Also i doubt that is the reason why he calls illumi.

If you haven't notice already their name begins with what ever the ending of their elder sibling. So Illumi Milluki Killua Alluka Kalluto maybe their grandmother is called Mikiaka lol weird name but just got it if you mix the letters they have simmilar off
