I don't know how to do this with the default Unity switcher, but you could use one of the other switchers compiz offers: Shift Switcher, Ring Switcher, Application Switcher, Static Application Switcher. They are found under "Window Manager" in ccsm (CompizConfig Settings Manager). You can disable the Alt+Tab binding for the switcher in the "Unity Plugin" in ccsm, and enable one of these switchers and configure their bindings as you wish.
There is a bug report about this for 12.04. The bug's status is Fix Committed, meaning the fix will only be available in the next release.
In the meantime I can only recommend gnome3. There ControlSuperd works as expected.
In case you want to give it a try:
sudo apt-get install gnome-shell
Restart, and at the login, choose GNOME (first in the list):
Where to find the show desktop keybinding:
open dconf-editor and navigate to schema org.gnome.desktop.wm.keybindings.
You should find a key named show-desktop with its current value.

For Ubuntu Dock shipped with Ubuntu 17.10 and later (with GNOME)
Well, Other answers are pretty old, so I think it is worth to add up-to-date answer. It is possible to do so right now and not too hard tbh (With Ubuntu 17.10 and it having Gnome).
Just use dconf-editor:
Navigate to org > gnome > shell > extensions > dash-to-dock and check isolate-workspaces
