Custom desktop environment for Debian/Ubuntu

view story

http://askubuntu.com – I like Unity a lot for its gorgeous dash and panel look, the global menu and HUD, the super+# shortcuts and that's it. I really hate it for the stupid launcher and its general inflexibility compared to almost every other DE (including Windows) as probably most of us do. I would much rather have cinnamon's or mate's modularity but I can't switch to these because I just cannot do without Unity's best features and Compiz as far as I know is unrivalled. So my question is how can I have some sort of Unity + cinnamon? Can I tweak Unity into looking more like cinnamon? Are there any tools out there (HowTos)
