If you want to do so, why not try another distribution with gnome or others preinstalled?
Maybe you are in favor of deepin-wineqq, then the procedure of installing another Desktop Environment is easy, just apt-get install blabla.
BUT what is not easy is the configuration.

I will probably install another distribution and then install the deepin desktop on it.
I like Deepin desktop but the problem is that there is no switcher interface to switch from a workspace to another

Enlightenment is running fine on Deepin!

See my thread on Ubuntuforums to install E20:

(use twenty.sh)

but only for enlightenment and a few others...
sadly it gave me a lot of errors when i tried to install gnome or pantheon.

actually there is, control+alt+arrows
