Here's a comparison to the real thing:

Looks like he gets pretty close.
In the meantime I have tried a couple of film emulations according to described procedure.
While some results are nice, I recognize that the approach also has its limitations.
Starting with Alien Skin’s "Exposure", the plug-in just seems to tweak the Red, Green and Blue saturation over abroad color range (as far as its color effects are concerned). It’s like stretching the primaries of a matrix profile. For example, numbers of R/G/B= +9/-2/+12 are given for Provia film. While this emphasis of Blue saturation is basically in line with my observation, I’m perfectly sure that it requires more color-selective tweaks in order to achieve the objective.
Further, the Chart Wizard of DNG Profile Editor which is used later on in described approach builds a LUT of hue/sat.-selective tweaks, but without calibrating the matrix primaries first. While this should probably be always done first in order to reduce the work for the LUT, it would make particular sense in this context here due to the nature of above saturation tweaks. But even if the primaries are manually adjusted before running the Chart Wizard and even if we had a better target file e.g. from scanned film, the resulting profiles are not really meant and were not designed to be really 3D.
So for the time being, Camera Raw Presets can be an interesting option.
