/var/cache/init-systems ?? Yes, I know it's just an example, but is a
very wrong one.

All OpenRC specific files/dirs like init.d, conf.d, runlevels and such
simply go to /etc/openrc/ , much like systemd with /etc/systemd. It is
really the correct way to do it.
Also, if one switches to OpenRC, you should forget about helper scripts
like update-rc.d.

If one switches to OpenRC from sysvinit, the install script would just
have to look for the enabled initscripts and their runlevels, and enable
them accordingly with OpenRC. Provided the initscripts are included in
the packages already installed. On that note, Gentoo's package
repositories might be a valuable resource.

On what could/could be removed, IMHO the old sysvinit scripts can stick
around because they will not overlap with OpenRC's scripts. The only
thing that comes to mind is the inittab and how it will be handled?
Perhaps just a symlink to /etc/openrc/inittab ...
