If I were to do it, I would install unthemed xfce first. Then install qtile as suggested by the wiki. And then follow my guide crib killing off xfwm4 to setting qtile in auto start and removing the shortcuts.
OR
I would install qtile community edition suggested my @pannet1 , and then add in xfce and xfce-goodies.
Try it out. I’ve never done that particular combo.
I’m interested in helping if you give it a go though. I’ll help the best I can.
