There's a way, which is overlaying 2 sprites on top of each other: https://www.reddit.com/r/Gameboy/comments/pntbwh/gameboy_color_sprite_limitation... Still not sure how you could do it in the GBStudio, but at least this could be a way to go about it

Yeah! The NES version of Mario is Missing! does that, and it's pretty easy to do in the sprite editor.
Just be aware that only ten 8x16 sprites can be displayed in one horizontal row.
