I don't think so that anyone has prepared "pack" with VMs for PWK, but there are some VMs on HackTheBox or in VulnHUB, that could be helpful for the mastering knowledge acquired in this training. Example list: [Hidden Content]
And to answer you question about differences between VMs for AWAE and PWK. Them are totally different, as the goals are different. In AWAE you are getting credentials to admin/root of VM, as you are about to perform source code analysis (whitebox approach), and on PWK you need to do enumeration and hack the VM from blackbox perspective. In PWK lab you have about 54 VMs to hack in different "networks".
