I would prefer a metatag-like solution to adding another set of tags like duo/quartet/etc... Something like what AkaringoP said, but not quite. Replace the girl/boy/other tags with counts that are stored for each post (6+girls becoming 6, etc...). Search for and modify those counts via metatags of those names. Add a metatag ("headcount", "chars", or whatever) that searches on the sum of those counts. Display those counts specially in the post tag list.
So "girls:3", "boys:<4", "chars:2", etc...
As for the mess of multiple views and whatnot... dunno.
if we are gonna do this, should we deprecate male_focus as well? either that or undeprecate female_focus, since something like "girls:>0 boys:0 others:0"/"girls:0 boys:>0 others:0" would be equivalent to it
more pedantically, having either "girl" or "girls" as the metatag is kinda iffy due to you know, searching for either a single girl or multiple girls
