Yes, but it's incredibly difficult and frankly the emacs devs have enough to do (and they do it well), and UI design is a very different skillset from programming. Frankly the learning curve for emacs is not going to improve, muchas we both might wish it.
The biggest problem is people want the benefits of freely downloadable software but mainly aren't prepared to give anything back. Go and assist with emacs or some other project.
