The reason necro/sham/sk/druid are always recommended for duos is because they offer maximum versatility, basically covering all parts of a group (tank/dps/CC/heals) in the minimum number of classes for as many situations as possible. You can duo any class combination you want, but as you branch out from these classes, you will not be able to cover all of the group bases as well as with the aforementioned classes.
You are basically asking a paradoxical question: What classes can I duo well with utilizing unorthodox tactics to cover all of the group functions? Any can work, but the ones that cover it best you've already excluded.
