Do any of these features exist?

If the below features don't exist and you think you can make them for me please send me a message with a price for making it. I can't pay much but I believe in rewarding good coders where possible.

1. Topics with no replies show as green. Topics with less than x replies show orange. Topics with more than x replies show as red. I'd love that. Is it possible?

2. Multiple avatars. Allow users to upload 3 different avatars and they can choose which one to assign to a particular post. This can let people reflect what mood they were in whilst posting.
