Well, that would be a cool project, but I'd say you were designing a
new PDP-8, and would be troubled by calling it a replica.
I guess if the big-board version (that shares only the schematic) can
be a called "replica", then so can one that shares the aesthetics but
not the schematic. To my mind, a replica should really have both (as
much as is feasible).
