Legend
The level-0 funnel adventure "Death-Slaves of Eternity" by Marzio Muscedere that I highly recommend does something similar. Because it is set in a classic Sword & Sorcery setting where only humans exist (no elves) it reskins the demihuman classes:
Elf becomes Cultist
Dwarf becomes Soldier
Halfling becomes Pirate
So now every character (and they are all human) have three new classes to choose from.
I've seen something similar in a couple Shudder Mountain con games (I think Brendan LaSalle started it) where:
Dwarf = Mountain Man
Halfling = Luckiest Son of a... You Ever Met.
