My theory is that Gems can eventually fuse with humans, the fusion between Greg and Rose just wasn't successful, because Rose didn't want to fuse. If Rose turned her body into light, and Greg jumped into her, maybe the fusion would've worked.

Steven was shown to be able to fuse with Amethyst without turning his body into light.
