Sorry, that posted itself before id finished writing lol. Cant remember what I was going to say anyway. 
I did it with the engine out, so dont know tbh. I expect the restrictions imposed by the alternator are morelikely to be a problem than the other bits youve mentioned. Access down the back is fairly shit at best, to take the whole system off youre probably looking at about a days work. Main issue is the studs and nuts on the exhaust flange, they tend to be corroded on and the whole thing ends up needing welding because once youve broken a stud the join will leak.
