I think all Imperial fleets will end up looking vaguely similar, choosing from a selection of workable builds. This is mine...

EMPIRE FLEET (300 points)

The Bomber Wing

• Mauler'' Mithel (15)
• Soontir Fel (18)
• TIE Bomber Squadron (9)
• Major Rhymer (16)
• Darth Vader (21)

A nice simple Major Rhymer flying circus. Possibly a touch under powered but still lobs plenty of black dice.

The Carrier

• Victory II-class Star Destroyer - Admiral Screed - Wulff Yularen - Expanded Hangar Bay - Warlord (131)

Wulff to allow me to only need to convert one squadron dial into a token at the start of the game (Plus Screed & Wulff are less than Tarkin). Warlord name to increase hit damage and I couldn't squeeze Dominator in. Maybe drop Warlord for Gunnery Team or Flight Controllers.

The Wild Charge

• Gladiator I-class Star Destroyer - Veteran Captain - Engine Techs - Expanded Launchers - Demolisher (90)

The usual Gladiator build. Veteran Captain for the late game if I need a quick fix, but can easily be dropped in favour of initiative bid or something else fun. This unit is there to shift focus from the rest of the fleet - this ship needs to die or my opponent will be sadface.

Perhaps swap Screed for Chiraneau?

Saves you 16 points plus it works well with your bomber idea.

With the points you can get some more fighters (bombers)

Alas Screed is a commander and Chiraneau is only an officer, If I shoehorned him into the list I'd still need to take Screed, Motti or Tarkin.

Promoting Chiraneau to admiral has everyone confused...

Chiraneu has always been an admiral, he was demoted for X-Wing. He was an admiral in the Decipher CCG.
