The only down side that I see is that the aliases will not themselves be

I don't see why this follows.  A CNAME from a signed into another signed
zone "uses DNSSEC".

"from a signed into another signed" neither klam.biz or .com will be in themselves signed, they will inherit the signing of klam.ca.
I did wonder about adding both a dname and a  cname for klam.com might work.

Something like:

klam.com    IN DNAME klam.ca    # this handles the subtree of klam.com
klam.com    IN CNAME klam.ca    # this handles klam.com itself


I have not tried it and my guess is that if it even passes validity checks it will produce unexpected consequences.
In the mean time I will stick to the single zone file for the moment.
Thanks on and all
