The actual circuit is a bit more complicated than just a resistor 
network, because it also does NTSC colour encoding. But you wouldn't need 
that for the 5155.

I've seen plenty of real IBM CGA cards on E-bay. Is there a good reason 
not to use one of those, and get the machine more original?

I don't know of any CGA scheamtics on the web, alas. Anyway, shouldn't 
you be designing it yourself rather than taking somebody else's work?
