Another great update, Gonzaga. I guess this new successory law will mean in the medium and long term a much lesser number of fidalgos/infanções. So, who in the hell is going to be granted with lands and positions in the colonies and the administration? The socio-economical implications, also because the odds are against the survivance of large latifundists, can be very interesting though with the time frame you have planned for the TL perhaps its effects can't be explored in depth (it's not a complain).
Cheers.
