I'd take the exact opposite position - it's not that there is a lack of information. Instead, there's an overabundance of information. Places like baseball-reference.com, baseballcube.com, etc already have most of this information (draft position, minor/major league stats, etc) in a data base. The work comes in parsing the data (for example, to do a regional study, do you divide the country up into 50 states, 6 regions, 4 regions, etc?). Coding the data would be a heck of a lot of work, but in this day in age, the data is most certainly there.
I also think there's some value in the study even though you claim that minor leaguers are handled differently than they were 10 years ago. You might find, for example, that over time, kids from (insert state/region here) fare better in their development than kids from the rest of the nation, regardless of the minor league operations. That would indicate that maybe the Little League / Pony League / AAU / High School systems at the local or regional level have more of an impact than originally thought. There's certainly some logic there - kids who are taught better at an earlier age are more likely to not have bad habits / techniques that lead to the inevitable injuries, etc. Conversely, you might find that there has been a change with the way that kids from state/region X have gone from being drafted to actually being a regular big leaguer. Some evidence there would give credence to the argument that minor league instruction is more important than finding kids from solid programs either at the junior high, high school, or college levels.
I like the Late Bloomer hypothesis that M2's working.
