Yes it's probably possible by switching out the rear wheel and shift lever. It won't be cheap, but it can be done.

well my thought were to buy the nexus 8 with roller brake and the shifter that matches, but the bike has a coaster brake now. do you know if things will just bolt up. i called nexus and they said it wont.

Probably not. The 8-speed hub is wider then the 3-speed and you may need a new frame.
