Rotary broaching is slightly less accurate (0.001" oversized broach, 0.001"-ish loss of concentricity), but my thought was that you can load the broach into the toolchanger and do it on the CNC instead of doing a secondary operation off the mill. That being said, the way your 4th axis is set up at the moment, I don't think it would be easy to integrate.
EDIT: If you are using a lathe to turn the initial diameter, you can use a rotary broach in the tailstock to broach the hex instead of going to the press.
