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. The problem is not if he can use Nen or not, probably he can. The problem is he sacrificied all of his TALENT to acquire that power. Like giving up all of your future potential in exchange for once burst of power and then loose everything. Did his lost of potential meant his mummified state? if so then he is healed now and should be back to normal but if it meant he sacrificed any future growth and Alluka only healed his physical body then he's screwed.

It means Alluka made him physically healthy but he has no potential for growth now, he would be an average joe at Nen.
