I know one automitive manufacturer who had been doing something similar
by integrating vacuum forming with RTV molding. The first step is to
make a vacuum form tool and use sheet plastic with pre-existing leather
texture. Then you can attach various clips (produced using SLA or other
methods) to the formed part. The combined model is then used as a
pattern for an RTV mold.
Also, our ESPOR technology can copy existing textured patterns into
micro-porous air-permeable aluminum molds for production thermoforming.
