I can answer that :-)

When installing Epoch, do it entirely extra-distro. Do not use the
package manager for anything. Don't remove the current init system,
just jumper around it by backing up the existing /sbin/init, and then
replacing it by what got built during Epoch make (obviously renaming
it /sbin/init).

Epoch is in no package manager that I know of, and therefore is
installed by compile. It comes with buildepoch.sh, which, for me, did
the job simply by running it with no arguments or modifications.

Plain vanilla gcc works just fine compiling Epoch. Just
run ./buildepoch.sh as a normal user. Then copy
compile_directory/built/sbin/epoch to /sbin, owner root, group root,
executable by all. You might also cp -p /sbin/epoch to /e , so that in
Grub it's trivial to put init=/e in the line when you want to boot
Epoch. In that way, you don't have to boot to a System Rescue CD, and
copy either the Epoch or sysvinit to /sbin/init, in order to toggle
your init system.

No Debian build script exists. Epoch knows nothing about Debian (or any
other distro), and Debian (or any other distro) knows nothing about
Epoch. Just use Epoch's buildepoch.sh, copy, chown and chmod the
resulting build/sbin/epoch, and that's it.

By the way, it would be about 10 times easier to do this on Devuan,
because you wouldn't have to decontaminate dbus and lots of other
software. Systemd adds a lot of cancer-roots you need to remove in
order to alternatively init. Try it on a VM, see how it goes.
