Holiday event suggestion for Easter/Xmas (based on puns)

I thought maybe it would be cool if GGG does something like an Easter Egg hunt or chance to drop some new items/uniques - perhaps an item that comes out of an egg during Easter for a duration of like 2 weeks or a month each year and call the event Path of Eggsile. These could be boss drops or achievement based rewards.

Likewise something for Xmas can be done with gift or wrapped drops and a xmas tree. I know it sound a bit corny but some games hold in-game holiday events and I don't recall GGG doing something like this in the past.
