Maybe it would be a little less of "DIY-lobotomy" (or "gender
reassignment", whichever you prefer :) if you install sid onto the usb
drive instead and leave your default system intact.
But then, if you are running buster and desperately want to
build your own kernel *now*, you could probably just replace buster's
gcc-7.2 with sid's 7.3 to keep you going.

​As it turns out I have installed debian on a usb before and booted it up successfully.
It did occur to me that you could advise the new users to buy a raspberry pi computer
and use that to run sid and then install the kernel on my from it.

Then I would have one machine which apparently cannot be infected with meltdown and spectre
with both sid and the spectre enabled kernel on it (raspberry pi) due its architecture
​and my PC running buster with the same kernel ported to it but I don't really need it because
I already have it in my Gentoo installation:
