Just finished a game with all destroyers, and I have to say it was pretty fun and ended up working way better than expected.

Game was 2k points, we did No Man's Land. Ended up tabling my opponent by turn 4.

My list was

Vanguard Detachment

Skorpekh Lord

Lokhust Lord w/ Res Orb

3X units of 6 Skorpekh Destroyers

3X Plasmacyte

2X Hexmark Destroyers

2X units of 6 Ophydian Destroyers

5X lokhust Destroyers

3X Heavy Lokhust w/ Cannon

My opponent was playing Red Corsairs with 1 Disco Lord, 2 Maulerfiends, 1 Leviathan Dread, and 1 Lord of Skulls, plus some infantry, with Huron and a sorcerer.

I was worried about dealing with the vehicles, especially the Lord of Skulls. It took a while to deal with them but the Lokhust Destroyers did a decent job of dealing with them, although I might change the 5 man squad to 3 more heavy destroyers with cannons.

Skorpekh Lord was my Warlord, but I'll probably have the Lokhust be the warlord next time, as the Skorpekh is kinda squishy.
