I had to implement exactly the same scenario with a CQ 5.2.1 instance 2 years ago.
ATG exposed product feeds via XML webservices. We attached to them through an OSGI bundle connecting to the webservices. Everything worked fine and without any issue.
you could could also use REST communication between CQ & ATG, this is CQ most common "language" thanks to Sling. It would be much lighter than to handles specific webservices management to be deployed on CQ.
hope this helps
Ignazio, can the catalog maintained in CQ5(can we display the content of catalogue by storing it in CQ5 rather than in ATG).Can u tell us a sample scenario for which you exposed a webservice and how u implemented that in CQ5?
