Site-to-Site VPN with dual ISP for backup/redundancy

Hi Experts,

Is it possible to create two site-to-site VPN with dual ISP on two ASA, for backup/redundancy purpose?  

Please have a look at the attachment.

Company B (right) has two internet links from two different ISP terminate on its two ASA. They would like to setup two site-to-site VPN to Company A (left) on the two ASA for backup/redundancy, so if ISP-2 or ASA-2 become unavailable the VPN can fail over to the backup link (ISP-3 and ASA-3), and vice versa. 

If this is workable could you please briefly advise how to configure the ASA? Thank you very much!

Regards,

Jacky
