In my opinion, no. Once spanning mechanisms go beyond two
base characters, it is no longer useful to try to treat
them as encoded characters, as it is increasingly unlikely
that appropriate rendering mechanisms will be available for
them.
An arbitrary-length spanning undertie or overtie is in
principle more related to other mechanisms of highlighting
arbitrary segments of text, such as underscoring,
overscoring, and the like. I think the representation of
such in digital text should be handled by style and
markup, rather than by seeking solutions in character
encoding.
