You will be surprised to hear that we already got that for one title! I dont know the english name but its the one you get for 30 minions that "follow you around" (it has mini-minifilia as symbol) - equip that title and even minions that wont normally react to emotes due to their charactaristic will do now!

That being said: I'd like to see more easter-egg titles like that! They dont have to boost your stats (actually, I wouldnt like that at all because your title would only become another type of equip then...) but something like... "Hey, you got the title from winning chocobo races - use that and your chocobo will move faster"
