Since Anakin is arguably not the main character in TPM yet we really need to empathise with his motivations, maybe you could insert his “binary sunset/broom boy” moment the night after he finishes working on his racer. We’ve known Child Anakin for a while but we haven’t really seem him resent his status as a slave, or a sense that he races not only because he’s a good pilot but also because it’s the one way he could be set free.

Maybe showing little Ani look onto the distance, with some ships and gunshot sounds heard across the slave huts at night.
That way you could replace Child Anakin boringly telling Qui-Gon “I want to be the first one to visit all the star systems” with a more emotionally resounding scene where his motivations are displayed visually rather than force-fed to the audience. That also would remove the midichlorian talk.
