I have actually played a list like this and had success. Obviously you need units on the ground or you're going to lose automatically, but the list relies on lots of podding units.
HQ
Swarmlord (2x Tyrant Guard)
ELITES
3x Hive Guard
Doom of Malan'tai (Mycetic Spore with Cluster Spines)
TROOPS
15x Termagaunts (Devourers, Mycetic Spore with Cluster Spines)
15x Termagaunts (Devourers, Mycetic Spore with Cluster Spines)
Tervigon (Crushing Claws, Onslaught, Catalyst)
Tervigon (Crushing Claws, Onslaught, Catalyst)
HEAVY SUPPORT
Carnifex (2x Devourers, Mycetic Spore with Cluster Spines)
Carnifex (2x Devourers, Mycetic Spore with Cluster Spines)
TOTAL: 2000pts
It's pretty easy to find things to change around, but the Swarmlord's there for +1 to Reserves and extended synapse range (in addition to his psychic powers and general badassery). Cluster Spines are on all the Pods since they have crap
BS, and the tons of extra blasts they're throwing out should help to take out nearby enemy infantry (they're sort of risky, but fun

).
