Dig it! Though I think you need some puppies for puppy duty (and hey, they benefit from Throgg's
LD, don't they? So beastly and themey

). I also agree that the shaggy could probably be points better spent, and more trolls the better ... So here's my shot:
H: Throgg = 175
C: 7 Trolls = 315
C: 4 Trolls = 180
C: 4 Trolls = 180
C: 5 Warhounds = 30
C: 5 Warhounds = 30
S: 5 Ogres -
MoN, full command, ahw, chaos armor = 305
S: 4 Ogres -
MoK, full command,
gw, chaos armor = 280

THROGG > Check.
MOAR TROLLS > Check. Specifically, a trollstar for Throgg to hang out with, with a respectable US24 for fear duty and outnumbering. Also a huge amount of wounds to sop up and mutate along.
PUPPIES > They do things! Check.
OGRES > Red ogres blitz with loads of S6, Green ogres go wiiiide and also smash things. The champs are kind of wastes of points, so if you want another troll somewhere there's 45 points spare (champ + champ + 5 extra points). Or a 6th green ogre, same points cost and gives you a fairly beefy unit (which I'd run 4-front, 2-rear myself)
Should be a fun list, loads of rampage potential.
