I opened it within minutes of finding it. It could be trimmed down to basically nothing VERY easily, and the cart slot is on a ribbon cable, I'm not sure if I would even have to relocate it. Is it a non-standard cart slot?
Pics! The cartslot, it is 60 pin I believe. Mine was. It plays famicon games, not nes, unless you just use a convertor. I just hardwired in a nes cartslot FTW!!!
