I can vouch that a CoCo 3 keyboard can work in a CoCo 1.  When I put a 
CoCo 3 in a mini tower case way back when, I had this spare keyboard 
lying around.  The chicklet in my original CoCo 1 wasn't doing so well, 
so I concocted a way to wedge the spare CoCo 3 keyboard into it.  I used 
a short length of ribbon cable with a card edge connector on the end of 
it.  The mylar is too thin to fit snugly by itself, of course, but I cut 
a little strip of PCB and stuck it in there with the mylar, and it made 
a good connection. Maybe I'll do a blog post about it, so people can see 
a picture of how I did it.
