I don't think it would work because Saturn discs have multiple rings to check, plus data beyond the lead out. That data may be either 00s only or nonsense, but it could be integral for something like keeping the laser going steady and looking for non-standard data at sector x.

If you've tried booting Saturn CDRs with the top off, you can see that the laser checks the area around 50min mark nonstop.

On retail games it goes past another (slightly visible) ring, pictured, and THEN it checks the outermost ring - but only goes as far as the black rim where it starts. THEN it boots the game.

So there is some hidden data which is completely unreadable by normal drives, and then the outer ring which CAN be replicated but doing so does fuck all because the authentication dies before it can reach the outer ring.

And all this is just speculation based on watching the laser. Truth is, until someone decaps and reads the ROM of the SH1, no one will know exactly how the Saturn protection works.
