Is there any way to add all apt repository of Debian based Linux distros on your Debian system?

Let's take example of Ubuntu and Kali Linux, both are based on Debian Linux. but many packages in Kali's apt sources are not available in Ubuntu's apt sources. But if we add Kali's sources and GPG-keys. Those package will be installable on Ubuntu directly by apt install. I need to add all apt repositories on my Debian system so that, I can install any package from any other Debian based operating system. EDIT: Okay, I know this is a bad idea. But what if I wanna force use it in a VM or to use it once then remove the sources. (Kali is an example what about other distros)
