Great idea Ben,
We are definitely willing to learn about the demand for such a theme. We are always open to work on tasks (concerning our tools) that are in a great demand within the community. I would like to share though that our primary focus (in terms of themes), will be on improving the current themes and make them consistent. However, we can plan working on a new Blend-like theme in the next quarter Q2 2010.
