I don't have the time to mess with this, but if I did, I would make it. So I'm just going to put it out and let someone else have the credit.
Anyway, someone should make a plug where you are a Wraith, and you run around defending wraith space, maybe fighting the krypt mind, keeping pirates from encroaching on your territory and help improve relations with Polarans.
Since the Polarans make all these biological goodies for their ships anyway, why not make it possible for them to make these goodies for the Wraith? I don't know about all the 'credits' and what not, I guess you could just pass it off as energy credits or something. The hard part would be re-writing the universe to be a wraith. Obviously you couldn't go into any bars, so descriptions would have to be changed, many outfits would have to be removed. A wraith couldn't put on a missile launcher.
The wraith could have one 'homeworld' which could basically be an asteroid that just host communal gatherings.
The polaris would provide the wraith with new techs - maybe some type of biological enhancement that would allow you to carry weapons such as missile launchers.
Wormholes could become more like hypergates, the wraith could have the ability to choose where to come out (I don't know if this is possible, but if you turned all the wormholes into hypergates that were all linked, but just looked like wormholes, this should work).
Anyway, plot would have to be developed further, but tell me what you think. And run with it if you want to.
