Relatively new to tyranids 1500 list. Swarmy List?

[kvnbaumann]

Hey I am fairly new to Tyrandis but have played several 1000 point games by now.  I am wondering how to make a good 1500 point list and especially one that is swarmy yet can still be semi-good and be playable.  The units I currently have are
1 SwarmLord
3 Tyrant Guard
13 Warriors (9 boneswords, 3 Stock, 1 Cannon)
2 Dakkafex
1 Tervigon/Tyrannofex
1 Harpy
26 Gargoyles
1 Pyrovore
1 Venomthrope
2 Lictor
17 Genstealers
17 Gaunts
8 hormagaunts
2 Rippers

I have money to spend and would love to make a swarmy list so probably the swarm box for buy.

Main question is what would be a good 1500 point list in general around these and maybe 100 bucks more of stuff and another 1500 list that I could make into a classic swarm list with the swarmlord leading the charge.

The swarm box would get you the 30 gants you need to make the Tervigon a troop.

30 gants (some with devourers)

Will be your core. You'll want shrouded so venomthropes or malanthropes are vital. Everything you add after that is down to taste.

Hormies and Gargs are both viable but bare in min you'll need solid synapse to protect them. Warriors can be a bit flaky but if you keep them in shrouded they'd be fine.
