The MC16 and MC18 are very similar in size, and the MC16 and MC18 R2/4J lowers are interchangeable, so I expect it wouldn't be too hard to get the top fairing to fit.

As far as I recall the MC18 Mk1 subframe fits the MC16 as almost a direct replacement, so R2/4J seat panels will then fit without too much trouble.
