I think aggressive tactics is better than esteemed leader. Endurance is one of the must haves on Grievous as he only has a courage of 2. Having 2 B1 units with HQ helps so after one unit uses it, the other one can use it next turn.
Maybe try this
9 activations 787/800 (so add in some upgrades you want)
Grievous (Endurance, Aggressive tactics)
Count Dooku (Force push, Force reflexes, Force choke, Aggressive tactics)
B1 Battle droids (5 in total - 2 with HQ and 3 naked)
BX commando (tenacity, vibrosword) x2
