Hello, I’m wanting to make my children’s costumes for next Halloween. My son asked to be Maui.

By that time they will be 4.5 and 1.5. I was thinking Maui for my 4.5 yo son and Moana for my 1.5 yo girl. But I do not want to offend anyone, we are not Polynesian. I will not be painting their skin or using any products to darken their skin. Is it offensive if I do this? I do not want to be labeled a racist, or my children be labeled that either. I know cultural appropriation and racism is a hot topic so I want to be as respectful as I can to other cultures.
