I don't have much to offer, but keep in mind that there's kind of a group within a group thing as of MoP. That is, you join a "party" {1} and then when you enter a dungeon etc, that "party" becomes an "instance group" {2}. You might have to look for that additional layer to get something like this to work.

Alternately, you can try using the Jamba Team Display, which always shows just your team and always in the same order. With all the display options they are pretty much basic party frames.
