THIS IS EXPERIMENTAL!!! DO NOT BLAME ME IF SOMETHING GOES WRONG!
So far this has been tested on LXDE and XFCE. This is a sister project to my FrankenKDE/E17 experiment.
To do this is very simple in LXDE or XFCE just go to run and type in "plasma-desktop" and there you go.
If you don't like it just log out and back in and its gone simple as that.
Can anyone test this out on the other desktop environments?
