Main problem is matching to differently nested constructs, like an
ottava into a repeat or triplet.  As a general interface to the desired
functionality this is not really good for that reason.  My proposal is
less likely to be affected since it wraps less, but for

\ottava #1 \triplet { c8 d \loco r8 } r4 c2

it could not be coaxed into working as desired either.
