I say, drop the Plasma and take melta guns, as your going close quarters anyway, you won't burn yourself, they cost the same.
I have to support Alexander with the SWS squads, as Bunny is taking to Vet. Squads from ten man which in my opinion, if you are going drop, or infiltrate, whatever, take little numbers of vets. The minimum should be ok. You save 80 points on this way. If you Vet's as a cheap SWS squads, then reduce your numbers. If not drop the Veterans doctrine if you won't use them on another way. HtH maybe? And buy SWS,they'll be your shooty units., cause you say you don't want to rely on Heavy Weapon squads.
as Henimann has also said, hoiw about a shooty HQ, with Plasmas and medic.
If not stick with Honorifica, or buy a HSO, and Power sword, give him a Plasma pistol, and four flamers and burn them.
