Can we do that? if yes...plzs provide me with the configuration .its ugrent..

Create route-map policies and then use them in NATTing.. This would help NAT to actually decide the exit path incase of failure.Definitely the source IP address 'll get changed in case of multihoming.

Thanks in advance.
