Given that {c16*2/3 c c c c c} can be interpreted both as \times 2/3 and as 
\times 4/6, the only other thing I can see is to look at beaming. I.e., a 
beamed group of 6 identically *2/3 notes will probably want a 6 over it 
rather than a 3.

I understand that c1*4/3 is not a possibility. I mean that there just should 
be some way to make the the tuplification ignore a note. Just in case someone 
wants it. The typical use of tuplification is to apply it to a score; so if 
there is one fraction somewhere that shouldn't be tuplified you will need 
_something_. E.g. it would be enough with something like 
\tuplify { ...
\excludeFromTuplify {...}
...
}
