I love the new Hornets. I run mine with 2x Pulse Lasers. Use the Warp Hunter to pop the Land Raider and then the Hornets shoot up the Termies. It works wonders.
Really consider adding the Wraithseer to your list. Would be very fluffy and very powerful. Keep your Wraithlords near the Seer and march forward with your screening Wraithguard. The Seer can give fleet and Feel No Pain to Wraith units. Yummy!
