I'd ask why? There's no requirement that there only be a single OI slice per disk. The installer and various other things push in that direction for some reason, but it's not a valid limitation that I can see.
Put rpool in a 2-way mirror using the s0 slices and then do whatever you want w/ the rest of the disks in the s1 slices. I setup an N40L w/ a 4-way 30 GB rpool in s0 and a 3.5 TB RAIDZ2 pool in s1. It took some arguing w/ the installer, but there's a general outline on the wiki. If I were doing it over, I'd probably make rpool a bit smaller. I can take a 2 disk failure w/o losing data. Leave a bit of unused space between the s0 & s1 slices so you don't need an identical disk to replace a failed drive and also some space at the end of s1 for the same reason. At the moment the disk utilities have conflicting notions of geometry which could be a problem if you need to replace a disk w/ one that reports slightly different geometry. This won't handle disks over 2 TB. Hopefully Oracle will release the GRUB2 changes needed for EFI boot soon. However, I can't see any reason one couldn't dual label a disk, boot using the SMI label w/ an s0 slice at the beginning of the disk and then mount the rest of the disk using the EFI label. It would require some code changes, but nothing complex. It's a bit ugly is all and won't work w/ a real EFI boot BIOS. But it would work w/ older BIOSes that don't implement the EFI boot spec. So it might be worth doing any way. Have Fun!
