Making bootable media from a running OS

I have a Kali Linux installation (VM) which I customized so much with custom bash & python scripts plus installing quite a few additional software,

I would like to know if it is possible to take this VM and turn it to a bootable media, say USB storage.

One way is to install Kali on a usb with persistence option to make the changes permanent, but it's just too much work!

"Please note, this is not the usual ISO-to-USB kind of thing, I'm looking for a way to make a bootable media from an already installed OS"
