Honestly,... only a few visible areas might need the level of detail that
might be achieved by photo etching. The rest could be layered bits of
styrene or acrylic built in a random manner. Say six to twelve inch long
sections three to eight layers high.
You could build practice pieces and when you got tired of it, then toss
it in a bin. By the end of a year you could assemble random bits that
would begin to match the silouette of the DS-II.
Once it was up on display, not many people would get so deep into the
model that they would notice a lack of doors, panels, base mouldings, or
light switches... They would be too amazed that there were floor levels at all...
