I definitely believe that clones could have a profitable investment, but the hardest part is actually making it come true. Most people don't embrace change too willingly. "Oh another facebook?" even if you mention the small extra features that you have that the original site doesnt. If you have a good sized number of people who could genuinely use your product (better if its a specific niche), then it would really help. I'd say do thorough research, ask friends and family, and definitely ask a few not so close friends as well for input (close friends and family will try your idea just because they're close to you, not always the best advice).
