Perhaps we had a better understanding of what you are trying to achieve we might give better advice. But based on what you have given us so far I would suggest this as a solution that would work
crypto map ABC local-address loopback1
crypto map DEF local-address loopback2
or if you really need to have just a single crypto map then my suggestion is to use the crypto map and to not configure the local-address. Then IOS will use the address of the interface through which it exits as the address for the traffic.
