I don't think chaotic evil necessarily means 'LOLDESTRUCTION.' It just means that you carry out your own goals ruthlessly; those goals don't have to be arbitrary human sacrifice. Chaotic-type Sith are generally independent and out for themselves, which I don't particularly think subtracts from their Sithiness. There's nothing in the Sith code that says you have to devote yourself to whatever the 'Sith cause' is accepted to be - if you look at the code, it's about self-improvement and power and freedom.
But yeah, a faction that causes chaos with the purpose of rebirth is an interesting concept. You'd have to be careful to show that the destruction had a purpose, but it could work.
