The community cannot be trusted to not exploit C1 Covers (I know of people who've even used Sunglasses and Phoenix Helms to cover exploit), so unless the C1 Covers were given a proper fix to prevent the cover exploit, then no, I'd have to say that C1 Covers should NOT be brought back. (I'd love to see fixed C1 covers back, much cheaper than spending tons of money trying for clean +15 or more, but I've seen too many people out there who think a glitch should be exploited, and not avoided.)

Of course, the old C1 Gang costumes, etc, being made into C2 covers, seems like a decent enough idea, I could go for that.  

Signed. Bring the old covers back even if they're in C2 form. We need a larger variety and these newer 1 piece costumes are no fun for mix and matching.
