Nihilus leadership good with Relics?

If you have Malak, you should put him on a Darth Revan team any day, would Dooku work as a substitute? the stealth he gets from his rework makes him much harder to daze and such, and his counters renew health like crazy, not to mention potentially ignoring protection. I used Nihilus lead before the palpatine rework, so as a second tier team instead of Traya lead, it might be alright? There are't enough separatist to use Dooku in a full team without taking away from something else either, unless I'm mistaken.
