Thinking about this further, I think it could work if I used a different 
proto for each site.

So Site A would use proto isp_a, Site B could use isp_b, and Site C 
could use isp_c.

Now, installing the "local" default route doesn't preclude the 
installation of default routes, possibly with a lower metric, from the 
other sites.

Is that what you meant?
