Wouldn't an interface like you can find in System  
Preferences>International>Languages work? Just take your base theme,  
and have that as the lowest one, and stack the others on top. The  
highest one wins if there are multiple definitions. If you have  
subthemes for PHP and say LaTeX they won't even overlap much with say  
"iLife 05". (You could even add checkboxes for easy on/off of themes.  
And themes would get there by drag & drop from a "all installed  
themes list").

Well, we could try to make things smart, where the bundle itself can  
check the color settings and do some math on the numbers, maybe  
invert the color or add some red tones… ;)

Yes, exactly. And, as a variation of this - lines in those margins,  
sou you can have certain blocks actually visible as blocks or you can  
have separators that are theme controlled, not lines full of "-" ;)
But I can also see this is a bigger task to implement but less  
important; most of the theme functionality would do something similar.
