That's a good theory - prophecies, not just in JOJO but a lot of fiction (and, you could say, real-life) tend to be rather vague.

Alternatively, before the events of Part 3, DIO could've had Pucci pop in a Stand DISC into his bone and figured out "If I combine this Stand ability with this disc, maybe some weird shit'll happen". Or DIO and Pucci were looking at a bunch of Stand DISCs and seeing how they could mix with each other, and DIO figured out the formula for some kind of super-powerful Stand.
