What you can do in Photoshop is limited by your CMYK setup, it won't let you 
to create ink combos above its allowable limits.  Also this is for CMYK RIPs 
only, and you would have to convert the image to CMYK; you couldn't apply 
this kind of stuff to an RGB image. And how do you know which CMY are 
components of black conversions (Under Color Addition, in this case) versus 
simply being colors in the image? I don't know of any way to increase the CMY 
component in four color blacks except through CMYK conversion, in this 
instance ICC profile conversion, and so the place to do this is through the 
profile, while the conversion is in process. And the place to control it is 
in the profile creation or editing software. This would also be more 
convenient, as you could apply it to RGB images, without having to convert 
them to CMYK first.
