What's wrong with using BFD for IP over Ethernet? You can put whatever control plane you want on top from simple static route priorities to full blown eBGP and everything inbetween.

Nothing, except that it's expensive to do on the carrier side and completely unsupported on any cheap CPE I know of. Aside from that is not a terrible idea, aside from being over engineered when you could just be using DHCP.
