I think a new class that was geared towards the Monk or Monk x Rogue might be neat. It would have to be something that could stand on its own and not take over any of the other classes. I also wonder about a class that would be built or geared towards using darkness more than light. Such as, when a darkness Subclass was equipped, it would only have four fragments spots to use for building. However those fragments could be more powerful than when the other classes used them. If a light subclass was equipped they could have six spots to help build-craft but the power would be a little less.
