As long as it's on the list, I'll toss out a few ideas for consideration.
How about a syntax like
Ii<inst_name_or_number><+|-><half_steps><:> ...
so that, for example, 'Iipipicl+2' would be used to transpose the clarinet
up a whole step. I'm specifically suggesting a disconnect between the MIDI
transposition and the existing 'K' transposition/key change mechanism
because one might like to introduce a \treblelowoct, etc, via in-line TeX.
Further, since it would be nice to be able to use \Ioctfinup ... \Toctfin,
etc, and have them reflected in the MIDI output, a local by-voice mechanism
should be available. I haven't come up with a clear syntax idea yet, maybe
putting, for example, 'Ii+12' in a voice to raise it an octave? And then
'Ii-12' to revert to the original transposition?
As I said, these are just some ideas for consideration.
