You just can't do that with RAID5. I seem to remember that there's a RAID 6
or 7 that handles 2 disk failures (multiple parity devices or something like
that.)
You can optionally do RAID 5+1 where you mirror partitions and then stripe
across them ala RAID 0+1. You'd have to lose 4 disks minimally before the
array goes offline.
