Could have it water jet cut on a machine with a tilting head for kerf angle
compensation. Water jet cutters tend to make the exit side of the cut slightly
wider so a 2 axis tilting head can push all that to the waste side.

Cutting internal teeth isn't something that can be done with a hob

to find a way to set up the equivalent on your CNC mill.

I don't think it is impossible, with the cutting tool in the rotary
axis, circularly interpolating around the blank.
It might be simpler to order one wire-spark eroded for a one-off or a
stock part from HPC or similar.
