Dark eldar standalone ally list

Hi guys,

I'm currently building and testing a 500pt/ 750 force of DE, the crutch is that I plan to use the force as an allied detachment for my eldar (mech). I would also like to use the dark eldar for smaller 500-750 pt battles as a standalone army, whist sticking to the allied organisation (so only 1 ravager etc    )

Here's the list so far

Hq

Succubus with venom b and haywire, rides with...

Elites

3x bloodbrides with haywire   
In venom, stock

Troops

5x warriors, stock
In venom with extra cannon

(Same as above)

Heavy

Stock ravager

500 on the nose   

I've used to use 3 incubi with the succubus but I have to drop the extra cannons from the warrior venoms which sucks, so I want to trial the blood brides as they give a bit of AT.

Scaling this up for 750 Pts I plan to use 4 incubi instead of brides, treat both warrior squads to a blaster add the normal 5 dog, 4 bird beast squad and a few goodies on the ravager.

Look forward to hearing tips/ advice and undeserved hatred
