Seems like a solid list except for the Succubi, i'm not fond of DE ICs. Maybe get a Llhamaean?
The only change id make is to drop two kabalite warrior venoms (you arent getting OS is realspace Raiders anyways) and get an Scalpel Squadron. They can allow you to null deploy agaist T1 Alpha strike lists if you win the initiative roll.
6 squads of 3 reavers with cluster caltrops and maybe heat lances if you have points to spare is definetly the way to go.
EDIT: Jesus, my spanish autocorrect butchered the post the first time around. Fixed
