if I understood your problem correctly you are facing design issues due to the DTO design pattern. Here is some litterature on it:
http://www.designpatternsfor.net/default.aspx?pid=99

You should regard your DataContract as a DTO. Since you wish to keep a 3 tier architecture and make minimum changes I would advise you to put all your WCF logic inside the BLL.
The problem you are facing is that at one point you have a WCF function (namely ListCustomers) which needs to return a datacontract while your DAL only works with "actual business" objects. There are two ways to work around this issue:
- implement methods in your DLL to convert DTO to business classes and vice versa.
- make the transformation as needed directly in your WCF service methods: call your DAL methods directly from your WCF service methods and transform the data on the fly into a data contract (usually easily done with linq).
