Each villager having a variant of Frostbitten, Burned and the eponymous Husk would be very cool.

• Zombie villagers could turn into Frostbitten when stuck in powder snow
• They can have a unique clothing texture depending on the transformation into any zombie
• A villager infected with a Husk will also be turned into a Husk and will be difficult to cure depending on the difficulty, its curing may differ from the normal mechanics
• Zombie villagers can also turn into Burned if they fall into lava, but it will be impossible to cure them
