That's a perfect approach Notes, exactly what I'm looking for. Using your method I can set up 3 different keyclones, 1 with just the 4 shammy based accounts with Brady Bunch maximizer, one with the same 4 accounts but the 3 smaller windows along the bottom of the screen, and then the last with 5 accounts, my main on the big window and the 4 shammies in the small ones. And when I'm solo playing my main (or even one of the chars from the 4 extra accounts) I'll just log directly in through my main shortcut, which goes to the wow folder with the huge assortment of addons.

On the dnp, turns out if you dig in settings around where you can change the pause button you can also set a key to toggle the dnp (or rr etc) function on and off, so now I hit scroll lock to suspend the DNP list, type in my password or even /cheer Randombystander, and can toggle it back off.
