Instead of thinking of them as running in tandem, I'd prefer to model it as letting you get pick get parts from one distro and parts from another. Part of the importance of the distinction is that there are some things you can only have one of in use as once, such as only having one kernel or one PID1. Bedrock does not abstract these away.

Yes, that's possible. You could, for example, hijack a Gentoo install then `brl fetch debian` and start using things from Debian.
However, if you
only want the kernel from Gentoo, and you
only want it because of recency with respect to things like spectre fixes, note:

If you're using the upstream kernel's build system - not emerge - and its .deb output, there's little value in building it on gentoo. Just build it on Debian.

Have too, no. It's quite possible on Gentoo, it's just a bit more work. Given your background, that extra work may be problematic. Given your goal, I don't see why suffering through that offers you anything.

Bedrock can let you use Gentoo's make with Debian's dpkg-buildpackage, but I don't really see how that helps over just building it entirely with Debian's tooling. Bedrock can also let you use Gentoo's kernel with Debian's userland, but from your description I think just using a Debian security team maintained kernel, or a backported kernel, or building a custom kernel on Debian, will provide the same benefits with a lot less complexity.
