a 30# touring bike really isn't a lot of weight, relatively speaking.

I would think it would be easier to go from 50# of gear to 45# of gear and less expensive, than to drop 5# off a bike since that would probably require a new bike. Of course, if there are any steel components on your Nishiki, you could swap them out for alloy and save weight. Stem, handlebars, or seatpost would be the 3 main possible places for an 80s Nishiki to possibly have steel components.
