I think it will fit ok so long as you don't need the dynamo. I would question though, why do it? The tin chaincases are easy to make oiltight with the club's improved seal. They look the part and are slimmer than the bulky alloy alternator chaincases. Edit: looking at george's post, it won't fit without machining out to fit the crankcase boss.
