Just buy a third party Famicom joypad with a longer cord. They plug into the db15 connector on the side of the Famicom.
just get a old nes controller cut the
wire and solder it to your Famicom
Well, due to the way that the famicom controller connects, that's gonna be tough. It's a connector, but one which appears non-removable. The FamiController doesn't solder straight to the board.
I've decided to just leave it be, or find a controller to plug into the extension port. I don't want to harm the authenticity of the thing; the more I think about splice, dice, and solder, the less of a good idea it seems.
Hudson soft (that funny little bee) company made a 3rd controller witch may or may not have longer cord that used the port on the front of the famicom. There's one on ebay right now with a rack of some sort to keep everything together

A months-after reply!
I bought a wireless 3rd-party controller which works great!
