Ralph, perhaps you can find the (probably few) places where
the software references the cassette output and patch it to
reference the speaker location, instead.

Input is a bit more difficult, since the //c doesn't have the
cassette input signal conditioning circuits.  You would need
an external amplifier to drive a transistor to switch a pushbutton
input (and the corresponding software patch to change the
cassette input sampling to the pushbutton input).
