I feel it would be a good idea to have a female voice Gon since he typically has a higher voice. In the 2011 dub he is voiced by a female so it wouldn't be that weird to do it here.

Gon grew up on whale island, orphaned but not without a caretaker. His mother is unknown though his father left him behind on the island with his sister. Gon grew up as one of the only children on the island and lived under the care of his aunt Mitto, though he always wondered about his father. He took it upon himself to take the hunter exam as soon as he could so he could go out and chase his dream on meeting his father while under the same profession as him.
