I dunno...My broaching experience has been limited to cutting keyway slots in gears, pulleys, etc. While in a production job, I've never cut a dovetail.
We did our broaching with a 24" geared arbor press, with a hand lever, .010" at a time. I never saw a dovetail cutter until I got into gunhacking. I now have some big ones, but they're for cleaning up milling machine/lathe ways. And cutting the adjustment shims for the ways.
A tapered dovetail...I don't know if that's even possible...Is it??? You would have to stop the broach at a specific point of the broach stroke, to get the same size taper each time...And have some way to push the broach back out in the opposite direction...
Beyond my experience...
