NoteNames will print the higher (and lower) octave names with
printOctaveNames set to true. It prints them as c', d', c, d, etc.

My question is: Is it possible to have the higher octaves print using a
different character, say C D E F etc rather than c', d', e', f'.

Yes, it is possible to do this by modifying the stencil of the NoteName grob.  I'm not sure what your system is, so I thought I'd show how you might convert Lilypond's pitch representation into the familiar C4=middle C system.  You could probably adapt it to your needs.

This only works with single notes at the moment, but I'll fiddle around with it some more.

Hope this helps,

David
