I have an i1Pro and I've profiled scanners with it before. I used to do tons of color management work. The best way was to measure your target then make a scan with it to produce the profile. Very direct. Profiling is a specific endeavor to whatever you are trying to get accurate. Something as simple as developing longer can change the target colors. Frankly I think for most people profiling is a waste of time.
These days I just do a simple thing which is to include a Gretag Mini Color Checker for a target in the scan. The colors of the Gretag are known and constant so using those with the eyedropper tool and a levels dialog with the appropriate settings on the three eyedroppers you can get excellent correction without a lot of hassle. I set the grey balance in Vuescan before I scan so there aren't any issues later. Very simple and works like a charm. The advantage to doing it this way is that the nature of the materials comes through.
