I saw Andrew Gearing climb Roadside Attraction using only a Yellow BD hex. Thats about the same size as a #2 camelot. So I guess you could do that.
You could always climb Foxfire...theres really no good placements on it so its good for a limited rack.
You could go up Nevermore on a rack that size. John Shrader did it in five pieces, one for each pitch. It was his first trad lead. He did it on a borrowed rack...mine.
