No, a PIX will not install two default routes, static or RIP.
I've tried this in the lab and it didn't work.
Come to think of it, I guess you could let both routers run
RIP, filter what they announce to the PIX and load-balance
based on that. A static default should take care of the rest
(and failure scenarios) and you could next hop it to a HSRP
address shared by the routers. I haven't tried this myself,
however, and you still wouldn't get inbound load-balancing.
FWIW,
