i'm thinking of starting an ogre kingdoms army but i want to make it a themed army. something to make it stand out, unique, etc.

i was thinking about an ogre kingdoms army based on slaughtering wood elves (although this is because i have a lot of WE bits handy to convert with and not because i know how i would go about this or because i think it would fit in with their fluff).

so does anyone have any other ideas?

thanks to all replies.
