If Alluka/Nanika had to seal his Nen, obtaining it back would mean he'd revert to the state he put the restrictions to, no? And he'd have to either find a way to overcome that part, or he'll die. Pardon me if I'm thinking dumbly here.

Otherwise, if it's merely "returning all back to normal" as I assume (and Ging mentioned he still has energy, he'd prolly make a remark if something was wrong with it) then Gon will merely have to reopen his pores and revise&retrain the aura usage. This is probably not something that would take long, as Gon does know all the techniques. I sincerely doubt the former is the case, but if it were, if he somehow overcame it he could maybe become a specialist. If not for that scenario, I doubt his Nen type would change.

Consult Killua before attempting this at home.
