I would like to see
Emerald Lightning/Judgement , either as a separate force power to normal sith lightning or the same where the effects would vary depending on your force alignment.
For example it would appear a green/yellow colour when LS but would have effects such as sapping will, Strength or force saves but not so destructive but when on DS its normal lightning but is more destructive but looses the 'sapping' effect of being LS.
