So basically three sets of paired workspaces. I'd look at the (pretty
sure it's darcs only) Actions.OnScreen module. You'd more or less
bind keys to exactly what you just described in English.

Something like (sorry haven't looked at the module docs in ages so this
is pseudocode/innacurate; there are probably helper functions that make
this shorter to write like viewOnScreen or sth like that)
...
("M-1", onScreen 1 view "2" >> onScreen 0 view "1")
("M-2", onScreen 0 view "1" >> onScreen 1 view "2")
("M-3", onScreen 1 view "4" >> onScreen 0 view "3")
....

Someone on #xmonad could probably help turn that into a list comprehension
if you want to get fancy and compress it into fewer lines.

good luck!
