Heroes again!?

I missed the Stonecutters event. So, of course I'd like to see it come back. From a practical sense, how much new content could they bring to the table for a 2nd event. For being the second time around, this event has a large amount of new playable characters and skins.

Halloween and Christmas events come every year and they have a huge library of episodes to pull from.
Super Hero's have been featured in many episodes and are getting a sequel.
Stonecutters is one iconic episode.
