Kabalites are much better than most give credit. They are cheap, very dangerous to anything without an AV (5 snap shooting at a FMC should down it) . That said, I agree... To many add ons.
Ditch the demi klaives, swap the disintegrator back to a dark lance, loose the flicker field on the incubi and warrior raider. Also you can loose the hydra gauntlets, PGL and agoniser on the wyches. This gives you enough to grab a phantasm launcher for the archon (gold with incubi), haywire grenades for the wyches, a venom blade for the hekatrix, night shields on the 3 vehicles without them as well as a blaster for the 5 man warriors (if I have added that up right!)
This makes the incubi more dangerous (great to dig units out from behind a defence line!) the wyches can take vehicles out as needed, the small unit of warriors now can multi task and you upped the amount of ranged AT. On top of that your vehicles should be more difficult to hit!
