You can already do option1 (if I'm understanding you correctly).  A
RAID10 array can use as many mirrors as you like (--layout n2 is the
default, meaning a near layout with 2 replicas, using n4 would give 4
replicas), and as long as the number of replicas is equal to the number
of devices, there should be no striping involved in the process.

Cheers,
