I still don't fully buy the logic that the SSD is too big for this game. I understand the arguement, and am I one who thinks an ISD is impossible for X-Wing, but the scale differences between that, and SSD-Armada are completely different. It still feels like the equivalent is asking for a Death Star, not the Executor.
It's worth noting that the Imperial has a command of 3... same as the Victory. So if a large ship cealing is Command 3 why the presumption that they'll jump to Command 5?
