I think this proposal is a good direction to go in. However, I think it is
still too early to put this in HTML5, and based on the quality of
implementations so far, it will probably still be too early by the time
HTML5 goes to last call in October.
However, I think something similar to what you propose (which is similar,
though more complex, to what Silvia proposed also) is what we should aim
for once we are ready to add more features.

I disagree that we should have author-controlled styling here. While I
could maybe be convinced to have something basic like colour and maybe
positioning, I think it is important that we let the subtitles be under
the control of the user and the user agent, as they are, for instance, on
TVs. Providing a way for authors to select different voices would make
sense, but if we allow arbitrary styling we are going to have all kinds of
problems, like lacking the ability to take subtitles and convert them to
braille without losing context, or losing the ability to trivially convert
subtitles for use in other contexts like TV subtitles.
(For the few authors who really want to go crazy, they can already overlap
HTML onto their <video> and do whatever crazy stuff they want to do.)
