Not sure what you mean by, "The bottom is fading fast", meaning the bottom end of your engine, are ypu talking about the seats, bottom of the doors or rockers?
As far as body and interior components, Cobalt and G5 stuff is all interchangable. If you're concerned about the motor, as long as it's the same displacement/ engine size, you're O.K. SOME parts of the motor are interchangable between the 2.0, 2.2 and 2.4 litre engines, BUT it all depends on what it is.
