In theory I'd like that a lot.

I'm now committed to two two-disk mirrors precisely because I couldn't
grow a RAIDZ (and would have to replace all three+ disks to expand it that
way); I started with one mirror, added a second when I needed it, and when
I need to increase again I will replace the disks in one of the mirrors
one at a time letting it resilver (yes, I know I'm not covered by
redundancy during that process; I'll do it when my backups are up-to-date.
 It's a home server and I can have it out of service during the resilver,
or in "no guarantee of saving changes" mode.).

And on consideration, depending on the expected lifespan of the system, I
might be better off sticking with the mirror strategy anyway.  Of course
RAIDZ is more cost-efficient, but disks are cheap.
