One way to do it is to accept a single large aggregate from both ISP's and
then point your defaut route to it recursively.  allow them to advertise an
aggregate they own like 12.0/9 and then redistribute "ip route" into your IGP/iBGP and use it to tweak your exit path. 
One the one hand you get only two default routes and on the other hand you
still get dynamic failover. IE: when dies so does the now invalid
default route.
