It's cirtainly doable, just not trivially by cutting and splicing :)
After all PS/2 mouse protocol, is very similar to PS/2 & PC keyboard,
I know of at least one CoCo to PC keyboard interface, and have built
such a beast myself with an AVR microcontroler and a couple of otehr chips.
But I guess that's what you meant :) :) :)

Depends exactly how the CoCo mouse actually works, you may be able to
get away with (as well as above mentioned microcontroler) a couple
of potential deviders and a couple of hi-z output lines, not ever having
seen a CoCo mouse it's hard to speculate :)
