Microsoft's SAMI caption format is based on HTML and CSS, however it is largely due to our experience of the shortcomings of such an HTML/CSS based format that Microsoft participated in the Timed Text effort in the first place.

I'm not sure what level of integration is being considered, or why CSS would necessarily be perceived as a benefit, since in my opinion there will need to be a strong barrier between the HTML and the timed text environments, for both security reasons and in order that the video/caption author's intention is not undermined by the HTML page author.

It seems that this is a reasonable to look at a new format since, in my opinion, none of the existing formats are satisfying (and yes, that includes Timed Text). The main problem being that none of them are based on HTML and CSS. I wonder however how you see this work interfacing with the HTML5 specification, ISSUE-9, and the work in the a11y task force.
Is your intention to bring an alternative proposal for captions to the task force? If yes, do you have a timeline in mind?
