I see what you are trying to do play a pretty much straight up Trooper build without Thrawn, with your limited collection, confined to that concept this is my critique:
For starters, General Veers is cheaper than Xizor so I'd go with him seeing as you are not trying to give any other stealth shooters Accurate Shot (Cad Bane) or using another version of Veers but I would go with Holo Veers myself because it is more reliable than +8 Attack. Second I'd take out the FSO because you are already giving the troopers Super Stealth so his CE would only come in to effect if they lost Stealth by Force Sense or It's a Trap in which case your squad has evade anyway so pick one Commander or the other not both. Better option is Paleon so that if your troopers actually land a shot it has a better chance to stick. Also it's better to get more Troopers in there. Also the Brutes are not doing much for you squad you would be better off with some Combine Fire support so your guys might actually hit something or some Uggie Demos to remove doors.
Something like this:
18 Rukh
17 General Veers, Hologram
16 Admiral Gilad Pellaeon
14 Scout Trooper Officer
104 Elite Scout Trooper x8
8 R7 Astromech Droid
16 Scout Trooper x2
6 Ugnaught Demolitionist x2
Rukh is a great cheap interference piece with a long range to give your troopers some breathing room.
Here is another way Imperial Super Stealth could also go:
With GA Thrawn it is easier to get the Troopers into position for the Fire Support to actually get off and the MT and +3/+3 is also helpful as well:
37 Grand Admiral Thrawn
17 General Veers, Hologram
16 Admiral Gilad Pellaeon
14 Scout Trooper Officer
91 Elite Scout Trooper x7
8 Mas Amedda
8 R7 Astromech Droid
3 Rodian Brute
6 Ugnaught Demolitionist x2
Now if you are just trying to find a use for Xizor's CE try this:
54 Cad Bane
40 Prince Xizor
32 Thrawn (Mitth'raw'nuruodo)
31 Arica
18 Moff Nyna Calixte
8 Mas Amedda
8 R7 Astromech Droid
3 Rodian Brute
6 Ugnaught Demolitionist x2

It is short on activations but Arica should be able to help you thin out your opponents squad with her Accurate Twin Sniper Cunning/Opportunist Blaster Barrage.
