If I can add some ideas to the fray...
Religion
We could try something truely different, no universal religions. Lets say there are twenty standard gods, but there are numerous variations or local cults. Thus a god of strength, could be seen as virtous hero or a thug, CE or LG, or any variation. And the gods, if they exist, are above the fray. They allow worship or appeasement without involving themselves in the acts. Thus each church is small and unorganized and powerless outside it's small circle.
Psionics
Have dead magic areas the size of 100-1000 miles or in specific regions but psionics flourish here. The talented are treated as scum outside of their boundaries. Could we fashion a psion vs magic war? Are the dead magic zones fixed, or could psions be killing traditional magic? Or even vice versa?
Alternative Realities
Fey lands directly bordering the outlands would be cool. Often times the gates between would vanish, and creatures from elsewhere would come into the prime. Could the fey be protectors? Or do they use guardians, good aligned prime souls to help maintain the gates?
Races
All players could be from one of four base-types:
- fey
- elemental
- outsider
- human based
(Hope this stirs the pot, and gets people thinking.)
