Would we be able to pull this off or would we sound different?

I was thinking, what if I created a band of seven members only, and we played seven different instruments. Which are electric keyboard/vocalist, electric guitar/vocalist, bass guitar/vocalist, and electric drums. Extra instruments are electronic small cymbals, saxophone, and clarinet. Would our version sound the same, maybe just a little bit more live, or would our version sound totally different from the original song?
