Naruto was also rather stupid, whereas it's shown repeatedly that Boruto is actually smart and capable. Boruto wouldn't need more than a week to get it finalized. Although i do think definitely more than 10 days have passed between the current bodysnatcher arc and the movie arc. Either way, Boruto would've been able to finish the technique, since he had it mostly under control already.
