Default Help Renaming APK pkg for phone

I have Team Blacc Out clear facebook but I want to be able to make several installs of the app. Basically run multiple facebook accounts from 1 phone. The real name is com.facebook.katana. What I want is just a few versions each with a different pkg rename for example:

com.facebook.k..... etc

I've tried many decompilers to achieve this like VTS but could not get a single one to work.
