Digital BW, The Print

I've been thinking about the possibility of using more than 1 inkset 
on one printer. That is to say, currently I use MIS VM quadtones with 
my 1160 using CFS carts. 

Would it be feasable to set up a different MIS inkset such as the VM 
Sepia with another set of CFS carts, purging the heads when swapped?

I occasionally have to pull a cart out to get it reprimed every so 
often, as long as one cart set was left in I would think this method 
would allow flexibility of inksets.

Thanks,
