There has been a number of lists looking to put warriors into night scythes recently, I personally don't see the attraction. In particular, why give up a ghost ark (which has AV13, more guns, and can repair warriors) for the ability to deep strike an AV11 vehicle. Also, when you get there you can't shoot anything outside 12".
If you really want to do this,
imho you need to give the immortals a night scythe - at least they can shoot when they disembark.
Did you consider spyders instead of stalkers? The stalkers are cool models in their own right, but most people take them for the twin linking advantage. However, I'm not sure you're getting much of a benefit adding 300pts of Stalkers so you can
TL the lanceteks and the Tesla immortals?
Spyders might suit your list better.
