Well, you can use Sidious' Dark Master ability on Durge, that way he can re-roll his save if the Skiff gets blown up.
Might want to squeeze in some Mouse Droids somehow though. Otherwise I think you'll have a tough time utilizing Whorm's CE successfully. If you wanted to, you could put Durge and a Mouse Droid on the Skiff, that way he'd automatically get the CE.
I think the Lancer Droid is also not really worth it in a build like this. Even with Mouse Droids, you'll have a tough time keeping Whorm's CE extended far enough to be useful with the Lancer. I'd go with a Human Bodyguard, and then some other sort of secondary piece, instead of the MSG and the Lancer. Maybe go with Deliah Blue, so she can Mobile/Twin/Cunning, and then also Repair the Skiff as necessary.
