Instar:
I didn't mean on the level of components, but rather overall ship shape.
Take a Norak Dreadnaught, for example. Each of the wings could be a hull piece, and if the design of your ship has a block of components (no matter what they are) that are arranged in a similar shape (3 square components in a row, forming a 6x2 block, for example) then the model used for rendering that ship gets a Wing Piece in that position.

Probably still not practical to actually do, but fun to imagine.
