I guess the simplest would be editing /etc/ppp/ip-up.local and
ip-down.local to alter the default route whenever pppd is coming up or
down.

#The defaultroute option passed to pppd when it starts up is what is
#meant by the previous email. So in your options passed to pppd you must
#have that keyword. The actual route may be stored in the peers file and
#be accessed when pppd realizes from the parameter you've passed to it
#that it needs set the defaultroute. Hope this clarifies,
