WAS 9 how override default provided MyFaces2.2 on Websphere Application Server V9

we are migrating from WAS 8 to WAS 9 and WAS9 is providing MyFaces 2.2 but we would like to override with MyFaces following jars

• myfaces-extcdi-core-api-1.0.5.jar
• myfaces-extcdi-core-impl-1.0.5.jar
• myfaces-extcdi-jsf20-module-api-1.0.5.jar
• myfaces-extcdi-jsf20-module-impl-1.0.5.jar
• myfaces-extcdi-message-module-api-1.0.5.jar
• myfaces-extcdi-message-module-impl-1.0.5.jar

basically we don't need WAS provided MyFaces , when I can uninstall myfaces on WAS 9 server, I see the MyFaces jars "Plugins" folder.

• removing jars from plugins folder is not working

any suggestions please
