Double bonding on RHEL 5 update 1

Hello,
I have a server with 4 NIC and i want to use Bonding Channels to benefit from my network architecture.
In fact, i want to create one bond (bond1) on eth0 and eth2 in mode 0 (load balancing)
and another bond (bond2) on eth1 and eth3 in mode 0 (load balancing).
After that, i want to create a bond (bond12) on bond1 and bond2 in mode 1 (failover).
the benefit of my architecture is to use load balancing and high availability. If the bond1 (eth0 and eth2) fails  the bond2 will be available due to the bond12 created in mode failover.
I will be pleased to find a solution for this.
Thank you.

I'd recommend mode 6 with arp monitoring. It is most auto-configuring of all.
Other modes are for cases it fails.

Are you sure you need actual hierarchy that ecactly cards work in pairs and fail over?
Imagine case load balacing loses one cable - and half of packets and hierarchy parent thinks it is up.
I guess mode 6 solves that by throwing away lost interface.
