When your headcanon relies on vague bullshit like 'newtype stuff' to make sense then it's a shit headcanon. I could just as easily say that the Rose of Sharon will crack open and out will pop Godzilla and Ultraman and Kamen Rider 2 and Eva Unit 1 because "newtype bullshit", but it'd still be prime grade bullshit.
Think your things through instead of running with the first hairbrained idea your fried brain comes up with.
