This would look like shit on a gunpla kit. You put an HG painted like that on a shelf and it'll look like you fucked up a diorama and scrapped it halfway through.

The painting techniques used for minis are generally not applicable to scale models and vice versa. It's why the first piece of advice for every Tau player in 40k is to buy an airbrush, because if you try to paint a crisis suit like you would a guardsman it'll look like hot ass. The purpose of
>this emulates the light source hitting the object.
is because minis are mostly very small and normal lighting conditions are more likely to drown out details than accentuate them and so you have to basically fake your own lighting. Gunpla don't have this problem, they're large enough to still show lots of detail and create natural shadows in crevices, so most gunpla shading techniques try to supplement what exists instead of creating shadows from nothing. You CAN do shit like that with gunpla and it can look great, but the vast majority of painters aren't going for that look at all. If you've got any kits you've done with that technique then I'd be happy to see what they look like, though.
