I agree, getting it lined back up is the trick.
There are only two ways to get the sprocket off, cut it off or pull it. However, I would say that pulling it would likely distort the cam as these are tubular camshafts with pressed on pieces with a ball bearing pressed through the tube after all pieces are in place to distort the metal from the inside.
Seems to me that cutting it would be the most likely option with a backing plate welded on, some machining to the sprocket and the plate to get them to line back up and of course the hole drilling.
Not a bad project if you could afford it. Should be cheaper than buying new cams by far.
