Are those definitely French people?
As for the names, you can of course change them, but what's the real difference between a profession and a name?
And intuition suggests that the balance isn't quite right; something like having a lot of recruiters and 2 killers for one mafia in a single night – it just doesn't seem right! And in both cases with 2 mafias, the city lost, but giving such an advantage seems excessive!

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
