Ok.

Possibly not, but initramfs/initrd does that all the times, i.e.
during boot, do something and then switch to installed system.

Yes, but this was meant as a "research" project, is it possible and if
so, what are the consequences.

One possible way to test this could be to have a greatly simplified
installer in an initramfs/initrd, which basically does a "precompiled"
install to a known system, and then switches to it and possible
continues from that.
