Would anyone be interested in organizing a build challenge?

I've finished exploring and experiencing all the existing content in the game, but am not particularly motivated to continue building a bunch of things just so I can walk around them all by myself. I had the thought today it might be fun and a good way to share our creativity by organizing a building challenge.

I have a private server I'd be willing to setup in creative mode for it . I'm not sure what we'd want to use for prizes, but I'd be open to suggestions. I'd imagine people would also want at least 24-hours positioned over a weekend to work on things, and then we could share them in a thread and let the community vote on them.

We could base the challenge around a concept (example) or just let it be free build. We could potentially ask the mods to help promote it, if they'd be willing to as well.

These are just my initial thoughts. Would would others think of the idea?
