Classful Network Addressing

Hello, I am aware that classful network addressing is a thing of the past and there are 5 classes.
            Prefix
Class A       0
Class B       10
Class C       110
Class D       1110
Class E       1111

If we wanted 9 Classes I’m trying to find the leading bits. Is this possible?

Thanks.

9 classes? No.
8 classes? Hypothetically, yes.  (keeping in mind the definition of Hypothetical is: by imagining a possibility rather than reality)

B 128-191 (1x)
C 192-223 (11x)
