How to mearge Bandwidth of two GRE MPLS Tunnel from two different Service Provider ?

I Have two Routers (Cisco 2821) connected one at my Main Office & Other at Branch Office. I have taken two MPLS Link from two different Service provider and created GRE Tunnel using MPLS Source & Destination IPs.

Now I want to merge bandwidth of this two different Tunnel and want to send traffic through the new Tunnel. Is it possible ?

What is your use case on

What is your use case on having a GRE tunnel (with encryption?) on the MPLS circuits? Are you using an IGP across the GRE tunnels? Are the MPLS circuits the same speed?

A single tunnel will be seen as a single flow and will be distributed across your paths as would a single flow (which normally would use just one path).

If you had packet-by-packet LB, the tunnel's packets should flow across multiple paths (although this can lead to out-of-order delivery and is generally not recommended).
