My first thought is that the Incubi aren't going to pull their weight properly. They're your only anti-armor assault tool, and they lack grenades so will have trouble dealing with units in cover. I think that dumping them would save you points that could get the Succubus and the Hekatrix Aggies, which would make those units more adaptable for general assault.
I'd also probably drop the Gauntlets and maybe a Wych or two and use the saved points from the Incubi to get another brace of Wyches, personally.
If you love the Incubi to death, I'd sack the Succubus to make an Archon with PGL as their escort, and shave some points off the Wyches in order to get an Aggie in there.
Another thought - S.Cannon on the Trueborn? I don't get what it's doing there. By the time you're at the point where the Trueborn should be shooting infantry - if the Trueborn are even still alive, they'll do just fine shooting Blasters as opposed to S.Cannons, and up until that point the extra Blaster will dramatically help them do what their primary purpose is; dealing with mech.
