A few extra ports don't hurt, really - it's a minor perturbation on
the steady growth of the ports tree.  From my point of view, it's a
good feature of the slave port approach that it makes the developer
think a bit about what combinations are really needed as separate
packages (since they have to do a small bit of work to set up each
one).  Anyone adding n! slave ports is going to quickly get noticed
and smacked :-)

You should be able to do that by just appending to SUBDIR and
CATEGORIES in a Makefile.local or similar.  It's been discussed
recently, anyway.

Or since this is for your own use you could just have one port and
write a trivial script that repeatedly packages it with your own set
of option combinations.
