Thanks They were/are going to be Gypsies, sort of... Gypsies or Carnival Folk (basically AoS Halequins)
from what i've read in this thread and on others, the only way it works is if you pick the best units from a general order army, then proxy/convert them to fit the Forest folk theme.
so i was going to get a Celestial Hurricanum and make that into my "caravan", then expand from there... witch alves as war/shadow dancers, sisters of thorn/doomfire warlocks, etc
basically, get a decent Mixed list, then think about which Wood Elf unit could represent which warscroll.
i even toyed with the idea of using Stormcasts as Mercenary body guards, either as it or by using the elvan bloodbowl team!
Ultimately i decided to go Undead, not exactly sure why, but it just caught and held my attention.
