I might be crazy, but couldn't you just prepend the route enough to
effectively poison it at ingress to 'backup-isp' ? so they kept
the remote path and never really accept the route from local until the
remote path is gone?

Not really - horrendous ASCII art below:

                         /                  \
                       /                     \
                  ISP_A ---------ISP_B
                     \                      /
                     \                    /
                   DC1         DC2

see, I knew I was crazy :( where is that halabi book when I needed it. Did
the original poster ever say if he/she was able to accept
incidental traffic to the backup DC ?
