Cinelli is the low profile classic in my mind. Not the profile of a Colnago, Bianchi or De Rosa - but as nice if not nicer because they are a bike that always means business.
Your steel frame is beautiful. Makes me want to sell my De Rosa Neo-P to make my rides all Cinelli. One thing I like about Cinelli is the ability to get posts/stems and saddles. YOU NEED TO DO SOMETHING ABOUT YOURS. Saddle that is. A gel cover is a band-aid for a bad saddle choice IMO. If you need the padding just get better knicks/bibs.
Why don't you find a retro Cinelli saddle and complete your project. It is mean't to be that way.
Oh, and some early 90'd Campy would help.... Shimano was never meant to be on a Cinelli. Love that frame.
