Black Ark Corsairs/Evil Elves "counts-as" help

I wanted to get some advice on building an army around the models I own.  I've been mostly collecting models that I like for a while now, having spent all of 6th edition being blasted apart and sewn back together.  I'm looking to build a force that uses the DE codex with some "Path of the Outcast" Corsair flavor.  I already have a few Raiders and a couple boxes of Kabalites and Wyches (oh, what to do with those Wyches....), but I'm having a hard time finding a battlefield role for the following:

10x Fantasy Black Ark Corsairs w/ handbows (+ a converted "epic Kaya" from Hordes)

Here are 5x Kabalites (Trueborn?)

Here are some "evil elf" type models I will definitely throw in

I also own the Mage Hunter Strike force from Warmachine and Tharn Bloodtrackers from Hordes, which I'd like to include. Reference pics:

Any thoughts?  The plan at this point is using all the Black Ark Corsairs as Kabalites (the monkeigh would never see the splinter rifles anyway) and use the Kabalite kit for Trueborn.  It's not a big deal if I can't find a believable "counts as" for the WM stuff, but I was thinking about using them as Eldar allies (I think the MHSF looks way better than Eldar Guardians).

Just for fun, here's my attempt at Fantasy/Grimdark Incubi:

I really like your models for the Incubi.

The Corsairs make for awesome warriors. I've used there torsos in the past. Since you already have the corsair bodies, what I would do is pick up some extra splinter rifle arms in bits and mix them in with your corsair models. They should fit rather easily.

Personally, I think the Corsairs make for better Trueborn/Sybarites. The capes make them stand out from the average Kabalite Warriors.

Lokhir would make for a great Archon, but his dagger should be replaced with a pistol.
The one to his left could be a Lhamaean, or a second Archon. No idea what to do with the assassin though.

The Mage Hunters could be used as Mandrakes. Their crossbows would actually fit for that role, since Mandrakes are now better at close-range shooting from cover than in close combat.

Other than that; yes, definitely more splinter weapons. If you like them dual-weilding, you can still attach the holstered rifles from the Raider crew to their backs.

HOLSTERED RIFLES!!! GENIUS! Also, I'm a bit stumped myself on what to do with the assassin model. He was just hanging around. Lurking. In the shadows and stuff.

Okay, luckily enough I have lots of rifle arms in the bin. Thanks for the feedback!
