Since:
- it8 targets are quite expensive (even those from color aid)
- they are not available for every type of film
- one usually has to rely (i.e. to buy) the profiling software with which the target goes along
- most of all for the sake of indipendence (and showing off: hey!, see what I can do?)
Would it be possible to go this way:
1 - get any reflective target for which the colours are representative (don't need to be known exactely, that, is you don't need a reference file at this time)
2 - shoot a picture of the target on the film to be profiled
3 - by means of a spectrophotometer (some are really affordable: could it be these would be of no use for the current purpose?) measure the image on the film and create a reference file for it
4 - scan the film
5 - write your own routine to create the profile from the reference and scanned files
Possible pitfalls I can think of are:
- a spectrophotometer good enough to this purpose could be too expensive
- although ICC specifications are well documented the icm format is hard to implement
- I have understood absolutely nothing about colour management and profiles
