Hi
what way is your current circuits setup as in terms of routing what protocol if any are you using, you can easily do it with 2 default routes pointing to each next hop , and set cef share load balancing but if you have critical sensitive applications changing the cef can effect them, also can be done easily with BGP if that's what your using , and another option is pfr

ip route 0.0.0.0 0.0.0.0 1.1.1.1
ip route 0.0.0.0 0.0.0.0 1.1.1.2
