Well, yes, it's possible, you can always rewrite the stencil, but it
would mean far more work than scaling durations.

I don't see a problem here.

Say you have an 8th: { \time 1/8 c''8[] }
This code creates a single 8th note with a one beam-segments

Now we want an equal lasting note with two beam-segmants.
So write the half duration, i.e. c''16 and double the it's length: {
\time 1/8 c''16*2[] }
Or use \scaleDurations: { \time 1/8 \scaleDurations 2 c''16[] }

Same for three beam-segments: { \time 1/8 \scaleDurations 4 c''32[] }

etc
Note, if \scaleDurations should be applied to more than one note, {
and } are needed.
Other examples are in the NR
