I think you were on the right path.

I would set up a custom routing table for traffic associated with the 
load balancer to use.  This load balancer routing table would use the 
load balancer as the default gateway.
You would then use ip rule(s) to determine which traffic would deviate 
from the normal default routing tables and use the load balancer routing 
table.  This could probably be done based on source port on the web 
server, or based on connection / packet marks in IPTables.  However you 
do it, you will probably need an additional routing table.
Keep going the direction you were, or perhaps post some of what you did 
try and let us take a look at it to see if you were close.
