Certainly! I'm not sure when I'll get around to actually doing it, but my intent was to create an emergency boot drive to send to my elderly family members that they could plug in if the system ever started acting up, and I'll build it in such a way that it'll be able to be booted as a Linux live USB, and also have a Windows partition for any tools that I might need for remote access and in-system diagnostics.
I've built a few scripts for the Linux bootable but I can't seem to remember where I stored that particular repo at the moment, so I'll share later.
Some of my stuff is up on my GitHub (same username)
I assume getting a persistent environment in a USB recovery stick is a bigger task? I'm imagining that, with your method, I would need to repeat this process any time I wanted to update the image or load specific new kernel modules/drivers?
Aren't there laws in place about consent and recording phone calls specifically?
