Ah, he is out and about in TOR? That would explain why there was no specific Revan body mesh - he just uses one of the standard Inquisitor/Consular player/NPC dresses. Although it looks like it uses a texture set that attempts to replicate his KOTOR robes. I had expected him to be physically plugged into some sort of machine.
I'll dig around and see if I can find the appropriate model and textures.
