Say, the cost of a VGA color monitor? 

CGA emulation on hercules is possible because it has a higher resolution than
the CGA graphics, and could be reprogrammed to display CGA resolutions.
VGA uses a lot more screen buffer storage a CGA card cannot handle.
Even with the loss of all color, I don't think it will be possible to 
work with a VGA oriented program on a CGA system. Sorry.

May be there are VGA cards that run all 16 color graphics and text modes on 
a standard (interlaced) 15Khz TTL color moditor? I don't know of any card
but guess it is possible. (they have also VGA to NTSC converters) 
But then again this is a hardware solution.
