You can do thin pools as RAID[1,5,N], just not in a single command:

|root #||lvcreate -m 1 --type raid1 -l40%VG -n thin_pool vg0 |
|root #||lvcreate -m 1 --type raid1 -L4MB -n thin_meta vg0 |
|root #||lvconvert --thinpool vg0/thin_pool --poolmetadata vg00/thin_meta

So yeah, it's not directly supported by the tools but it does work.  I 
would not recommend it though as I doubt it is very well tested.
