Yes, a digital design like that would probably work. With the density here, you could do multiple SIDs, a VIC II, CPU, all the support chips, HDMI output IO, and probably clock it pretty high. For multiple SIDs, they can be multiplexed rather than duplicating all the logic N times. 

For the mixed signal approach, you’d need to build your own op amps out of the primitives the PDK provides that match the analog behavior of the original. It would never be quite right, and it’s easier to just match the behavior of the original filter with a digital filter.
