This is going to be of no help to you I am sure, but maybe someone
else reading this who knows the internals better might have an idea
based on:

http://lilypond.org/doc/v2.14/Documentation/internals/balloontextitem

Such as i there was a way to 'expand' the annotation-balloon around
the grob and then use something like annotation-line = #f to only
print the balloon then 'maybe' (lots of ifs and buts I know) y-shift
the balloon accordingly to get it centered.

IKTWH!
