While it may work, it doesn't really makes sense. Your default gateway
should be the one that is used to connect to networks that aren't
explicitly specified in your routing table. 

So, in your routing table, you should have two entries, one specifying
the gateway for the local network, and a second specifying the default
route (the gateway to the Internet).

Take a look at:

Skimming past the bits about the actual Linux implementation, and
focusing on the IP routing bits.
