At first glance (it's bedtime) I'd say:
Shooty haemo + 9 warriors + raider.
Give your Archon a webway portal. Stick him in a raider with 9 of the wyches.
Remaining infantry can come out of the portal.
6 reavers is always amazing, loads of different stuff you can do with them.
DE wise, more transports! That's also my main downfall. A ravager if you lack anti-tank, and taloi are a heap of fun.
I dunno anything about craftworld pansies, sorry.
