It wouldn't matter because all it would have done was change the price maybe
a dollar.

Hint: You don't have have the traces tied to all the lines. The 6502 and
6507 were not much of a price difference. Even I could have got a 6502 for
$3.00. The rest of the design would have still been the same. It you only
wanted 4 KB, all you do is tie traces (to and from the memory)  to only 12
pins. Only have 12 traces.
