I usually use the Etho TARDIS Exterior whenever I play The Dalek Mod, its my fav exterior!
I always wished it, and other exteriors (like the Gizmo, Blocktor, etc) also had BOTI Doors, just like The Doctor's TARDIS's and a few others (like Ambient's, Epsimo, even the SB-129 TARDIS!)
I've done a quick photoshop as proof of concept, its pretty much just a retexture of the Coral Doors. I don't really know how difficult it is to program, model and actually make the BOTI Doors, but if its as easy as retexturing an existing door, it shouldn't be too hard... right?
