^please tell me you are joking
NJO Luke could waste anyone, he would beat Sids with one hand tied to the opposite leg using a butter knife instead of a lightsaber
If you want to know why, read some threads with NJO Luke in them, they have tons of reasons as to why he could beat Revan, Exar, Marka etc, and if he can beat those beasts, he can sure as hell beat Sidious
