Hi Jon
For what it's worth, when I stripped my engine I took the camshaft out with the gear in situ. I then rested the gear on the oak "soft" jaws I'd made for my vice and used a brass drift with a sharp strike from an ordinary (i.e. not tiddly and not lump) hammer to separate the two. It's the sharp strike that shocks the taper apart, which explains your lack of success with a rubber mallet. The brass drift gives you a larger target to a aim at and the brass avoids the risk of fracturing the threaded end of the camshaft. Important to have something to catch the camshaft as it will exit the arrangement quite swiftly!
I would be very cagey about applying a puller to the outer rim of the timing gear. It's the impact that parts them, not the pull.
Good luck.
Colin
