NO.

you can't bond two interfaces connected to different ISP's.

best you can do is limited load balancing, and/or use source tagged 
routing via ip rules to change gateways.   its a mess to get right.

Hi

Here is documentation that may help
http://lartc.org/howto/lartc.rpdb.multiple-links.html but as John mentions
it is painful to get right.

sadly, that document is like 15 years old, and hasn't been updated.   
the basics are still valid, but things like how to integrate that with 
RHEL startup scripts?  nada, you're on your own.
