I do not think so :)  In a nutshell, your service needs to connect its
stdout and stderr to a pair of different loggers; that can be done by
fd-holding and chainloading, and is how s6-rc internally implements its
piping (well, funneling) mechanism.  However, s6-rc only connects the
stdout, so the fd-holder needs an amount of additional configuration
whether you use s6-rc or not; that amount will be a bit big without
s6-rc, but it is surely doable and even scriptable.
