I would imagine what you would need is a 3d modelling system. Since all features of the tooth and the toothspace converge to a point, you could simply scale down your basic "1d" profile and translate it. Then use cross sectional surface to create the surface. This is then readily machined in a 3d cadcam such as OneCNC.
Actually, you will not be much ahead with the 60 degree endmill. You would be better off using a small ball mill to cut the profile.
Here is a quick view of what I mean. This is the toolpath preview from OneCNC. I did not take the time to make a custom toolpath which would create converging tool lines, but that would be possible also.
