Intellectual Property VS Story/Continuity with MORE

While working on an area of the D'ni cavern I hope to have ready for MORE. I got to thinking about the difficulties in making the continuity of Fan Created Content and Cyan Content synch up. Until now Cyan has at least outwardly been speaking of strictly story related and age related things. (We can't add onto A'guera, but we can create new areas of the Cavern outside of already established areas in both Uru and the books, we can't make ages mentioned in Cyan's books and games, but we can make ones written by the D'ni) And such of that nature.
Here's my thing. How. Take the cavern for instance, while each area has its own unique architecture, most of the Cavern shares the same look. (The Textures are reused etc.) But thats just the aesthetics'. What about things like Pedestals. Lamp posts, Nexus Stations and Nexus Pedestals. Throughout the city and cavern they're all the same. How are we going to create realistic new areas of the cavern, that look like they belong in the cavern if we can't use the staples of the cavern. How are we going to make areas reachable through the Nexus without making Nexus Stations? Won't the new areas kind of stand out and not look like they belong in the cavern?
So here's what I'm thinking, perhaps we should bring this up to Cyan. Ask permission, in terms of keeping the new areas of the cavern created by the fans, looking like the same architectual style of the Cyan created D'ni areas, a repository is needed. Basically for the cavern alone, to keep the look of it the same throughout, a repository of models the textures associated with them. Not a free reign to the fans kind of deal. But a small repository where fans can download things like Nexus Stations, Pedestals, Lamp posts etc, to put into the buildings and caves and tunnels that they'll make for the cavern. So this way, while the fan areas will have their own textures, supplied by the fans, they'll also look like they belong in the cavern by including the staples of the D'ni architectual style (Like the sign posts, the pedestals etc.)
Any thoughts?
