Packaging of PlayOnLinux

Hello, I want to ask if PlayOnLinux could be packaged to Fedora. This program has list of proprietary programs which are not downloaded but could be installed if you give it setup.exe file. Also it downloads Windows redistributable when user explicitly wants to install program (which using this redist) or given redistributable. If this is not "legal" in terms of Fedora how it's differ from OpenSource software which are using not-OpenSource addons? Example of this could be https://marketplace.firefox.com . I think it's sad that this good LGPL wine prefix manager software is not part of the Fedora and I like to change this. Thank you for answers, Jirka Konecny
