The LK would be the most logical ink to replace with a very light ink 
if you're using QTR.  If you print only glossy papers, then MK could 
also be replaced.

30/70 is the standard dilution, but you have some flexibillity there. 
Glop would be the dilutant you'd want to use with that inkset.

If you wanted to replace just one ink -- LK -- then you might want a 
blended ink that would come close to the tones you usually print.  
The UT-RC inkset ( http://www.inksupply.com/r260_blackandwhite.cfm ) 
has the most recent blended neutral inks.  If you started with one of 
the light inks in that inkset, you might consider UT-RCC Y position 
(still a relatively dense ink due to its targetting the 1.5 pl 
printers) and dilute it something like 1 part ink to 5 or 6 parts 
glop.  To equal the lightest inks we use, it'd have to be diluted 
more than 1:10, but a 2200 really does not need the super light inks 
something like my 7500 needs.  On glossy papers, RCC prints 
relatively neutral in the highlights; on matte papers RCN might be 
more neutral.
