Best idea yet. To drive the part you could cross-drill the dead-center bar and then run a bolt through the cross-drilled hole and the holes in the yoke.Mount a bar in the chuck and part-off then cut a 60 deg point using the top slide set to that angle. You can make this new "dead centre" bar as long as you need.
The point will be perfectly centred until you remove it from the chuck jaws.
For driving dogs I've used a muffler clamp around the work with a bar welded on to engage a chuck jaw.
Yep that spline end is likely hardened, so you'd need a carbide tool. However, it is also an interrupted cut; carbide is not great for impacts like that.
I'd consider a mounting a dremel tool with a cutoff disc onto the cross slide.
Be sure to cover all the machine ways/slides to avoid abrasive dust getting in.
Also consider a shop vac hose mounted to collect most of the dust.
Good luck!
Please let us know how it goes.

By the way, great pictures and description explaining exactly your problem!
That makes it real easy to understand and offer suggestions.
Do the cross-drilling before you turn the point, of course.
