You can accomplish that without the need to customize the .conf file
names; you just make, eg,
/etc/postgres/myconfig/postgresql.conf/etc/postgres/yourconfig/postgresql.conf/etc/postgres/herconfig/postgresql.conf

(plus additional config files as needed in each of these directories)
and then the postmaster start command is
postmaster -C /etc/postgres/myconfig

I see no real gain in flexibility in allowing people to choose random
names for the individual config files.  Also, it'd defeat the
ultimate-fallback approach of doing "find / -name postgresql.conf"
to figure out where the config files are hiding in an unfamiliar
installation.
