Do the Schwinn! It won't be heavy when you are done with it.
I have an electroforged 77 Schwinn framed bike. It has the heavy forged fork, 32mm wide rims, steel handlebars, Brooks saddle, Coaster brake hub, and a solid rod of 6061 for a seat post. It's down to ~26 lbs from ~38.
If you build that bike up with modern light "normal" components, unlike what I've done, you should end up WAY lighter than that.
I thought you said it was an 88?
EDIT: I just read up on the 1979 World Sport. It has steel handlebars, steel rims, steel rear hub, kickstand, and both chain rings are steel. You should have no problem getting that thing down to a more reasonable weight.
