A lot of vore games are modern-day themed as well as more sword and sorcery types, so for a 'generic' pack I think it'd be a couple from each category, and then furry/human and male/female as the other major divisions.
So I'd guesstimate...
Male medieval human/furry combatant (For example, a Guard, barbarian, cleric, wizard)
Female medieval human/furry combatant
Male medieval human/furry noncombatant (For example, a Bartender, peasant, merchant, miner)
Female medieval human/furry noncombatant
Male modern-day human/furry combatant (For example, a soldier, sniper, police officer, medic)
Female modern-day human/furry combatant
Male modern-day human/furry noncombatant (For example, a teacher, minister, politician, homeless)
Female modern-day human/furry noncombatant
For about ~16, presuming one human and one furry from each category. Examples given aren't meant to be exhaustive or anything, just examples of what I mean. Of course, it could become more exhaustive by doing more from each category, different colors/races/species of human/furry, you could throw in a sci-fi set, yadda. But I feel those 16 would be a good core.
...now uh, that said. If anyone made any kind of a set of battlers, even if it was just 'one' that would still be very well appreciated.
Making things is a lot of work, and I'm not trying to undermine that by saying 'it must be 16 things' haha.
I like the two you've drawn ^_^
(This also reminds me that I haven't looked into "Being the Bad guy' in months and months. I should address that error! C'mon, Chuck, time we got you killed a couple dozen times.
