Replacing stainless sheath on standard can

[GS5uk]

Basically moving on to bigger and better things with a 2005 gfs650 bandit. I'm part x-ing the gs and want to take off my devil can. If I buy a cheap scuffed up original can is it possible to remove the stainless sheath and attatch  the one from my original can as it's in good condition. I'm away from home at the moment and cant remember how the sheath is attached. If its pop rivvetted then surely it wont be very hard to do??
Let me know what you think guys..

I thought the cover was welded on.

Yeah,IIRC the original sheath is welded in place and it doesn't go around wrapping the whole can ,cheap piece of *blip* !
