That's definitely an option--doing it with SMT components could even 
come very close to the size of the original.  There are also 
transistor arrays, if close matching is desired.

Given that the original was modular, I wonder why the copy didn't 
implement that aspect.  Certainly one could have each type of module 
on its own PCB.  Core would be a different matter (can one even 
purchase monolithic sense amps anymore?), but a concession to modern 
technology might not hurt too much in that area.
