Redundant Cellular/wireless backup

Hello experts. I would like to pick your brains for a solution that will achieve what I am in need of.

I currently have a MPLS network connecting our branch offices. When one of these sites goes down, I am able to take a wireless device onsite, change some routing, and have the site back up and running through the wireless device (Fortigate 60B).

This is achieved through IPSEC VPN on the Fortigate. This solution works well, but I would like to extend this a bit in order to achieve a truly redundant connection.

Currently, when the Cisco 2821 goes down, I replace it with the Fortigate device and the Fortigate becomes, for example, where the 2821 would normally be

This works well assuming I change the routing and that once the MPLS network connection is restored I have to change the routing back.

However, is there a way for both to be running at the same time? Say, the Cisco 2821 is and the Fortigate is If the 1.1 goes down, is it possible for the routing to simply take over and the traffic then flows through

Again, is MPLS - is IPSEC VPN.

Any suggestions? Is this possible?
