A word of support, it's a mess at present.
And since I was doing something related I'll post it here too.

My goal was to merge initscripts, systemd, scriptless sysv and my own init,
with focus mostly on foreground daemons.
The result, however, seems to be pretty close to your proposal,
with uniform (generated, in fact) initscripts, and possibly also
uniform pid file handling.

long(ish) description of ideas behind this:

Sysv-style configuration is missing atm, the plan was
to pick any variables from .run files (see netsnmp/snmpd.run)
and write them to relevant /etc/config.d/*.conf files.

The limiting factor is that any non-trivial variable handling,
basically any conditions, are not going to work well with systemd
(example: package/tvheadend/S99tvheadend).
And I feel better about residing to simple ARGS=... vs dropping
systemd just because of this.
