I wouldn't narrow this to morphs: I'm thinking about "instanced groups" in a sense. Where you can put any kind of elements together, and just copy-paste them as you wish, but you retain parametric capabilities with a very light footprint.
This could be applied to larger scale workflows, reducing the need for hotlinking, with larger flexibility.
