Um that shouldn't be happening, the restore will mask out the RAID parts of the chunk tree and it should work just fine. Are you using the most recent version of btrfs-image? If this is happening it's a bug and we need to fix it, but I've restored several file systems from users with raid0/10 file systems onto a single disk and it's worked just fine.
