What about models? i guess we have 2 options, maybe it can be edited in editor, or larian will post plugins for 3dsmax/blender.
In preview of editor it was told we can edit textures and models right in editor..
We'll need an (unreleased so far) GR2 converter for this to work

Civ5 uses a similar format, so its exporter might be able to work with D:OS, but I haven't tried yet.
Editing the generated stats .txt file seems to work as long as it is edited *before* a companion is recruited
Editing it after recruiting has no effect, as after recruiting companions became PCs, and PC stats are persisted in the savegame file (unlike NPCs)
