I think many people are still working with Righteous options....
My buddy and I are still playing the Warforged Greatsword Righteous/Focused build (sadly not TWF for the dual AS procs) and I am thinking of changing our PDK/Charisma 20FvS (AoV/WarPriest+100% damage build) into a HE FvS with Righteous Weapons which could be Scimitars or LongSwords (though LongSwords could be centered fairly easily)...
Compared to something like "Whirlwind Attack" I don't think that "Whirling Steel Strike" is too Feat intensive especially depending on your classes/race...
If you like the idea of "Righteously Centered TWF" I would study the mechanics & feat requirements in this build:

If WSS is still too much of a barrier, if you go Kensei I don't think you need WSS and can use pretty much any weapons... In addition to WSS, I believe you can also be "Righteously Centered TWF" without Kensei fairly easily as a Drow using Righteous Shortswords with the Ninja Spy enhancements; Ninja Spy may be synergystic with Rogue.
