Has anybody tried it? I played a really rough game against Tau the other day where my opponent fielded a Riptide Wing, which blew up quite a few Venoms over the course of the game and even won combat and routed close to a dozen Reavers. Pulled ahead in the end because of the resiliency of the Dark Artisan, but otherwise I was very close to getting tabled.
The thought struck me that for a small point increase, you could run a Raider with Torment Launchers instead of a dual-cannon Venom. Against most heavy infantry a Disintegrator does just as well as two splinter cannons (though it does fall short against hordes or anything with a high invulnerable save, of course) - you'd want either a Raider or Ravager with Disintegrators so that you don't have the mismatched Torment Launcher/Dark Lance combo, or Tantalus for its 5pt Launchers. Reaper gets them for 5pts as well, but its lack of an AP2 weapon doesn't make it seem like the ideal platform to me.
Combine with all the standard Freakshow tricks like Armor of Misery/Mask of Secrets/Coven formations, and by packing your troops into Raiders instead of Venoms you could probably force a morale test on just about every single enemy unit each turn, some with penalties. Granted it doesn't work against Fearless/ATSKNF, but my local meta seems to be really shifting away from those two rules - even the Marine players are all over the 30k ruleset lately.
