I did this with this exact team as well so the strat works, only rng i needed was when Kabuto had to take Guy hits and Guy needed to one shot him lol, Hinata took some hits every now and then but her passive kept her alive most of time, Kabuto was main culprit for me when it came to failing. I was 24k~ power as well back then, 5 star Kabuto/Hinata and 3 star Naruto.

I would say you need 22-3k power minimum or you won't kill Asuma fast enough or need way to many retries for good Shark Bomb crits.
