Vegan x beagle or Bega (town in Australia).
Is a person from Bega a Beagan?
I'm pretty sure people would hear "Vegan" as in "Hi, I'm vegan" and be thinking 'Erm that's nice, me too, but what's your actual name?'
Also too close to 'bogan' which is a type of Australian chav (sorry to sound judgemental there, not sure how else to explain).
Sorry OP.
