Basically what you want (I think) is for your IP masquerading to
round-robin connections or some other load balancing strategy.  That
sounds doable, but I don't know exactly how off the top of my head.
Check out the lartc site referenced above for some ideas.

I've got two connections upstream (a DSL and a Cable).  I "load
balance" using static routes.  Connections to some destinations go one
way, to other destinations they go the other way.  The biggest problem
I had was routing inbound connections to internal machines.  On the
outbound reply, normal destination-based routing often sends them out
the wrong interface (not matching the inbound packets) causing the
connection to fail.  I solved the problem using fwmarks and associated
ip "rules".
