That should work. If you run eBGP with each of your providers plus iBGP and HSRP between each of the two routers then that should protect against WAN failure scenarios.

HSRP is often used as the first-hop redundancy protocol of choice. There are others such as VRRP and GLBP.

VRRP has the advantage that can be configured on any vendor device, not just Cisco.

GLBP provides packet balancing, in other words, not all packets are handled by the Active router.

For more information on HSRP and how to configure it, please refer to the documentation:
