Alright I'll allow it, but I can't guarantee he would be the focus throughout so it might not be a bad idea to make a second character if you're willing.

Also so looking for what you guys think.  Since the big spoiler I had in the opening post was Tadashi Hamada joining younger brother Hiro.  The idea being he ends up in the fire getting chemicals on him which end up saving him but mutating him.  I was debating between either Sunfire or Giant Man having found idea sketches for both of them.

Giant Man the idea being he never quite gets full control over his powers and thus SHIELD keeps him around for studying to help him figure it out.  Putting him in the Young Avengers program as a 'we're helping you, now help us please' measure essentially.

Sunfire would work in a bit of the same way, only this time he would join them more voluntarily.  Plus it would make more sense given Sunfire was in the original Marvel Big Hero 6 series the movie is based on, and again him going into the fire.

Either way, Hiro hears the news, begs and pleads with SHIELD to let him join as well.  Reworks his suit combining in microbots and flight (The first he only does VERY cautiously, and puts in many more safety measures against anyone else controlling them), and lets Baymax go back to his loveable medical bot self (Since I can't imagine Tadashi would be completely cool with the idea of his medical bot turned into flying kung fu machine.)

What do you guys think?
