Yes, the C88+ "13-5" (13.5% Eboni, remainder clear base) approach is 
like the MIS EZ inks in that it uses only one dilution (in addition 
to the Eboni MK).

One advance I've made since the MIS EZ write-ups is that highlight 
smoothness can be significantly improved by using only a single 
channel (color position) at the beginning; the inks start one at a 
time.  Curves written to do this can easily be dropped into ICCS 
(Create ICC-RGB).  I don't think this system benefits from further 
partitioning -- that is with inks -- if the sequential starting 
curves are used.

No, MIS EZ has a single midtone density.

One dilution -- to maintain the system you need a bottle of Eboni and 
the ability to mix a base (or buy Eboni-6 and mix).

My 2200 with C-6 is reliably churning out cards as I type this and 
work on other printers doing other things.  C-6 has, so far, been the 
most reliable, cheapest and best system I've used.  (But, of course, 
no guarantees from me as to what happens tomorrow.)
