Once a son takes over as king, the brothers become royal uncles and no longer count towards the 6 heir limit.
I see no reason to kill anyone off for their uselessness ulness you're in danger of having them inherit the throne. Also, even as uncles, they DO count as sons if they are the king's brothers. You'll have to wait until the new king dies and his blood son becomes new king. If he dies before his his oldest son is of age, the next brother will take over. Only when uncles are taken out of the line of succession do they stop counting as sons.
