If a Druid is still an elf and can either walk on two legs or ride a unicorn (meaning both models are acceptable since in both cases it's an elf), then the situation with genies is different – if you give him a genie model, everything is fine, but if you give him a standard hero-mage model, there's a clear inconsistency because a hero-mage is a human, and a genie is a genie!
Блистает там воздушностью прогалин.
Но между кедров, полных тишиной,
Расщелина по склону ниспадала.
О, никогда под бледною луной
Так пышен не был тот уют лесной...
