Yes, that gives the same output as in Graham's solution:

Both styles in my sheet music from the region.

A problem with the latter is it is going to be cumbersome to write  
subdivideBeams changes in every measure.

So the ideal would be to have more general solution, that fixes these  
things once for all. - It is complicated problem, though.
