If that works for you fine.

I must admit, for automated tests I set the one to test as the default
booted kernel.

If you really want to bisect you might want to go a step further.
The tool to drive via qmeu is "autopkgtest-virt-qemu" and it has
"--qemu-options=".
That said (I never tried) you should be able to build (e.g. by bisect)
a valid kernel outside (make sure that it has all modules in a way to
work without having the kernel actually installed).
Via that you could use qemu options:
-kernel
-initrd
-append
as needed.
Once set up in a way to work you could really bisect through that.
OTOH that might be just as much work as installing them manually a few
times - so your choice what you prefer.
