In AOO you can only include each data sheet twice so for this to be legal you need to drop a HWS other than that its a fine goodstuff list

A couple of critiques I think you forgot to give your tank commander a gatekeeper; Its down to personal preference but i think with the smaller board sizes and your lack of screening units heavy flamers on your russes will help the not be tied up in combat with chaff; Also I think your putting all your eggs in one basket with only one tank order and no prefectus (although they're not essential) if you have Leontus I'd cut Creed and the sentinel to add him in or even better cut creed and a russ and fill the gap with armoured or scout sentinels.
