Digital BW, The Print

I don't own either a 7000 or the RIP software, but am considering a 
larger printer for B/W. So, with this software RIP I could 
theoretically use TWO sets of inks, say two blacks, two cooler tones 
and two warmer tones. Then selectively turn off the cooler tones if I 
want to make a warm tone print? This sounds very interesting.
