I agree on swapping the orcs out for moar goblins, in the name of synergy if not theme. Skarsnik is totally a thought, but I think you can also get away with:
Night Goblin Warboss [4]
Night Goblin Shaman [4]
+ extra goblins or fanatics [2]
Armament on the warboss is up to you, though I'd probably go with the moon-slicer for the D3 wounds and
this model. His command ability is pretty legit, especially on archers!
I like the idea of 2x1 or 1x2 fanatics, though on the flipside both of those units need as many more bodies as you can pack into them. 11 in each is a start, or 12 in the spears, because fighting.
Also, not sure on which banner is better, as they're both solid positives, but unfortunately neither work as well (or at all!) when the enemy gets close. I guess the Bad Moon always works, since shooting can always happen? Though the Bravery is legit for these poor sods.
