I'm trying to put together a Kromac theme list, more for aesthetics than play. I want to include both the old and new gorax models, as I think they would look great as Tharn Ravagers who have warped a little too far for a little too long (I may add some of the decorative elements from the Ravagers).
Unfortunately, there are really no corresponding large warbeasts that really follow the same theme; the warpwolves and satyrs just don't really have the same feel. So, I'm trying to think of how to convert one (or more) of the existing beasts into a kind of uber gorax. Right now I'm thinking of using either the feral warpwolf or warpwolf stalker with tails, spikes, weapons, etc. removed and with BIG rocks added.
But my sculpting skills are pretty much limited to minor green-stuffing, so I need to try to find a solution for the head. I think using the new gorax head might work, but am not sure about how to make it all fit.
