I am just not convinced wrestling the college season at 143 vs 141/149 would have this astronomical advantage that you all are saying it would. Zain grew into a nice sized 70kg wrestler (154lb). As he matured, 143lbs just was not the right size for him. James Green walked around at 160 (according to nhs) so he was too small to be a true 74kg (163 lbs) and too big to be a 65kg (143lbs) based on how lean he was. We have had great success at 97kg without have a college weight class at 214lbs. Your doctrine is being developed based on a few tweeners for weight classes. Wrestling the college season at 141 should allow for a young man that is maturing to grow into 143 lbs for senior level competition.
I also admit that I would have no problem with aligning the weight classes for NCAA to fit the international standards better but it is true that there are more wrestlers in those middle weights than the upper weights. I do not think that college wrestling needs three weight classes above 200lbs.
