That sounds excellent. I'm a core contributor and know my way around the client asset building. I've been wanting to look at the streaming logic for quite a while so I'd be happy to help you with code reviews and suggestions. I'm also curious to try out a bit of Go, so feel free to illustrate with Go code.
I think the biggest contribution would be to set up an E2E test for clustering and user sessions working reliably. We have to longstanding issues which have been hard to nail, and a stress test solution would be a huge help. It would also show how mature the codebase is.
Feel free to raise an issue or pull request.
