Digital BW, The Print

For some years I have been using the Cone Warm Neutral inkset in an 
Epson 1160 CIS setup with very satisfactory results. I use MIS FS in 
a Epson 3000 with equally good results. (The 3000 is using the plugin 
which is set for the Cone inks; it gives a good, linear greyscale).

I would like to switch from Cone to MIS FS with the 1160, because the 
inks are MUCH less expensive. But I am highly intimidated by the idea 
of setting up the CIS afresh. When Cone changed the formula of the 
black to Portfolio Black a while back, I did not start with a new 
cartridge and everything that involves like they told me I had to: I 
simply switched from the near-empty old-formula bottle to the full 
new formula, and it worked fine.

Of course MIS says I have to start out with fresh carts if I want to 
use their ink, but I suspect this might be a bit of CYA...what is the 
worst that can happen other than needing to print a bunch of flush 
prints and perhaps adjusting profiles?
