I have seen simple 15-pin hi-res to 9-pin CGA/EGA converters in the
big computer discount stores.  Whether they would solve this problem 
I don't know.

But as far as Apple RGB cards are concerned, what makes you think they
are all 15-pin?  I have a Video-7 Color Enhancer for the //e which is a
64k/80 col/RGB card.  The output is standard CGA or compatible.  I have 
it hooked up to an Amdek Color 722 IBM CGA monitor  and the color is
better than the SVGA monitor on my PC.

I think there are some faqs or correspondence on Ground that explain that
the //e cards were CGA compatible, while the output from a /c or /gs was
not (memory lapse possible).  I seem to recall that your are right about the
/gs output being analog, but everything else was digital. 

Anyway, I just plugged the Amdek monitor into the RGB card and it works
fine.  And it has multiple color text modes to boot!
