Creatures to use as Hellion skyboards?

Hello everyone,

I'd like some assistance with my army theme. The idea is that my archoness/succubus ( I haven't decided yet) and her followers were sabotagd by her rivals on a raid on Catachan (or some other jungle deathworld), stranding them there. But instead of dying as expected, survived, becoming 'one with the jungle' and going a bit feral, using the jungles deadly resources to thier advantage. Ultimately to ambush another kabals raid on Catachan and using their webway portal to bring her array of deadly plants and beasts to carve out her own jungley part of Commorragh.

So far I've given my wyches suitably jungly bases and paint schemes and started a raider covered in greenstuff vines and lichen. To go with the theme I'd like to fairly large units of Beast Masters and replace certain vehicles (skyboards/reaver jetbikes) with animals/beasts of some kind. For the jetbikes I thought of using the Lizardmen terradons. But for the skyboards I cant seem to find a flying creature thats the right size. I thought of the using wood elf warhawks, but I'm not sure how big they are, from the pictures I've seen they look a bit too big. Does anyone know if they'd be suitable? Or have any idea of any other flying creatures I could use? Or have any ideas I could impliment in my army?

Thanks

My 2 cents,

having been in a couple of jungles, a natural critter is a bat.

I would try using the GW fell bats. Those would be suitably dark and realistic, for a futuristic sci-fi game with evil space elves and transdimensional beings.

Already done that, I am getting them painted up as we speak.

I'll post pics later!
