What might make this work nicely as an experimental shard:
Make resource gathering/looting nicer, such as implementing similar looting/gathering ease of life as in main EC, but do so in the CC on the NL, somehow.
Make content that brings folks together, such as they did with the Void Pool recent event.
Somehow, use EC functionality and ease of life with CC graphics for the NL.
Allow rapid skill development for player characters via some new functions.
Allow rapid skill development for pets also, Plus change scrolling from white PS scrolls to different items that would allow your pet to got to 120 at different skills/magics.
If this shard is going to be wiped yearly, then completely different training for characters skills and pet skills will be needed.
