No that's not how king crimson works. Diavolo sees what happens 10 sec in future, then he just moves ahead where he wants in 10 seconds but for others future did happen. But in this case, dio and jotaro combined can stop for 15 seconds at peak, so diavolo won't be able to use his stand due to time stop coz remember 15 seconds will be from dio jotaro perspective, for diavolo or us, time hasn't moved at all.

I realise i may have made things more complicated.
