Clannad 64 hit and disfiguring sunohara

[crazyjosiah]

now i understand that   for something special to happen  the order has to be Fuko-Koumura-Nagisa..... but i also understand that the 64 hit can be achieved after the koumura route    and i really want to save nagisa's route for last,, but i'm wondering, if i take a detour  after the koumura route to do the 64 route and then replay the tomoyo route for the disfigurement of Sunohara and the appearance of ninja fuko, will it effect that   fuko-koumura-nagisa order to where id forfeit that special thing that was mentioned?
