You're removing the boiler/stack/engine on there? Too bad; the Dr. Loveless that came with the Derailer tank didn't have the engine, but I've often seen this version left intact, with something like an Armorcast turret added.
Not truly 360 degrees, but it's small enough we'd never quibble about it.
I'd think a suspended pilot house would be damn tricky to fit in the small space between the legs.
Wish I had a derailer one handy to offer to swap. I've got one, but you've heard me whine about finding stuff before. ;->=
