Hello,

\shiftDurations happily accepts a negative second argument,
like: \shiftDurations 0 -1 { c1. }  If there are not enough
dots, it just brings the number of dots to zero.

It is unclear to me how one could do better given that

\tuplet 3/2 { c8 d e c d e }

and

{ \tuplet 3/2 { c8 d e } \tuplet 3/2 { c d e } }

are different things in spite of all notes having the
same played durations.

So perhaps use tags to convert the non-dotted to
triplets manually?

Regards,
Jean
