It's kinda hard to imagine the unique effects of Rasengan variants, only the basic properties of it. For example, who could've been able to guess that wind release Rasengan (Rasenshuriken) will explode into microscopic blades damaging the enemy's cells? Same with Boruto's Vanishing Rasengan effect. But it's not like I cannot imagine anything at all. For example, earth Rasengan with weightening/turning to stone effect akin to Oonoki's techniques or water Rasengan producing slicing water currents like Tobirama's severing water wave jutsu on a wider scale. There's a lot of place to speculate.

P.S. Yeah, you need a great talent to create such a technique, but the series have actually presented a lot of talented characters.
