N700A DCC Sound

[GeorgeHInch]

I recently received the Kato N700A 4-car set and installed the DCC decoders in the cab cars and the power car. I was considering adding a DCC sound decoder into the non-powered car. I believe there should be enough room under the floor plastic if I removed the metal weight. I'm curious if anyone knows of or has created any sound projects for any of the Shinkansens yet.
