It's actually a little easier than that. If you use a RIP, and make 
CMYK profiles, all you need is ColorshopX from Xrite. It will generate 
a BO profile from the CMYK profile, or measured values (I've never 
tried from measured values). The RIP may not be able to use the profile 
directly, but you can convert the image in an editor to the BO space 
and then print. From what little I have done, this makes a big 
improvement to the image by putting the highlights and shadows within 
the proper limits, also should help with any non-linearities that your 
particular printer may have.
