It's possible, but a nuisance.  The UT7 and MIS Pro inks are totally
compatible.  They are the same inks, in fact.  One is just a blended inkset
of components of the other.

If you're running a 2100, have you tried QTR with the OEM ink arrangement?
At 2880, the 2100 may be smooth enough for you with just the LK and MK or
PK, with the LM and LC doing the toning.
