As a quicker workaround, have you tried setting up a 'dressed down' cinerender scene? Nothing fancy, just the most basic settings with a 'general light' lamp set up with infinite distance/strength to light up the interior views. You should be able to get a render in under a minute for these kind of views.
Or save them as 3D documents with colour representation settings.
Or take the saved JPEG to a photo editor, apply some filters and overlay a sketch render to go for a handdrawn presentation look.
