Not 100% certain I understand what needs to be done (despite the cool graph!).
We’re holding a component and want to get its mesh and assign it as the mesh of the paper slot?
Or is it going to be more complex, because it often is?
Stick with me, trying to wrap my own mind around it 
In layman’s terms:
- we (the player?) hold a sheet of paper (grabbed component, right?)
- we interact with the chamber (an actor?)
- if the interaction is valid, the chamber now holds the paper
- the chamber must own or have access to the paper so it can access it, too
- we will extract the paper
How close am I? And, if so:
- is there ever going to be something else than paper we can hold and stuff in the chamber
- is the paper / items supposed to run logic of their own (hold data - as in, the paper has dynamic text and pictures that can be updated)
