FreeBSD's kernel + busybox as a userland, is it possible?

[prp-e]

First of all, I'm aware that FreeBSD is not like GNU/Linux and it delievers both kernel and user space in one unified base, but I also am aware of past projects such as Debian GNU/kFreeBSD which used FreeBSD's kernel and made it the kernel for a GNU system.
Now, I am thinking of those minimalistic Linux distros which use BusyBox as their userland (I think Alpine is like that) and I'm curious about is it possible to do it with FreeBSD kernel as well? I do not have any specific use for the final product in my mind - except for a learning project - but I think it may be a minimalistic operating system which can be a rescue disc, a container OS, or just simply something to explore for curious minds like myself on Github.

The way I understand it busybox in ports does not replace FreeBSD userland in totality.
sysutils/busybox

BSDBOX was a project to replace userland with BusyBox style system.

Look at the files in /rescue, that's a similar environment as busybox. There's basically only one real executable in there, all the others are hardlinks to the same file.

Busybox sucks at security. Their Bugzilla is always down. On Alpine I install the GNU utilities.

the /rescue binary is made with crunchgen(1) fwiw.
