Yesterday, I took notes from the websites about this (mostly Ben Rubery's and Planetside:Ships of the Fleet). Since no one expects an Executor class Super Star Destroyer or a Death Star to be anything but a monstrosity that creeps slowly across the mat and can barely turn, I decided that the Imperial class Type I Star Destroyer is the largest ship that would reasonable. Anything bigger would simply display the megalomania of its builder, which fits the storyline, but is of little use to anyone trying to play with these ships. I have tryed to follow the original source as closely as possible, but I did push some Weapons Batteries together to save space and trim some Weapon Arcs to make them fit. I could have made this smaller by using a higher Tech Level, but I think that they would have built these as simple and cheap as they could.
Pardon me if I have to post this in short bursts by editing, the Library computer keeps logging me out of the Forum and deleting the post, if I attempt to write at length. I had this completed when it did this to me, and I am somewhat vexed.

Special Equipment: Cargo (200); Carrier (1316 Capacity; Launch: 4, Recover: 2); Critical Hit Save (3+); Damage Control (4 dice); Hyperdrive; Stormtroopers (24).
VBAM Statistics:
Cost: 24, Maintenance: 23/6 ~ 4, Defensive Value: 16, Anti-Ship: 14, Anti-Fighter: 18, Command Rating: 9, Command Cost: 4, Basing: 14; Hyperdrive.
I had 206 Space Units left over and gave this ship Cargo (200). If you prefer, you can use this space for 6 Vehicle Bays and 4 Tractor Beams which I left out (the Tractor Beams in this background setting do not work like the ones in Armada, they just draw things closer or push them away). You could even use the extra space to give the ship 4 more Shield Facets which would raise it's Combat Rating to 2096 CR and raise its VBAM Cost to 25 and its VBAM Defensive Value to 17.
I substituted Stormtroopers for Marines at the same cost. The Capacity is 1316 because that is 14 Flights of T.I.E. Fighters. This may seem like a lot, but in this background setting, a warship is supposed to be simply a big box of fighters. Now, I should give you something to put in that box.

T.I.E. Interceptor: Size: 6, Speed: 14, Attack: 6+, Defense: 1; ROF 3; Interceptor; Capacity (63).
T.I.E. Bomber: Size: 6, Speed: 8, Defense: 2; Capacity (66).

These are my best interpretations of the printed sheets that I found for these.
The standard loadout for an Imperial class I Star Destroyer was listed by one source as 1 Lambda class Shuttle, 1 Stormtrooper Transport, 1 Assault Shuttle, 7 T.I.E. Fighters, 2 T.I.E. Interceptors, and 2 T.I.E. Bombers.
