I'm not entirely sure what you had in mind by a separate template. If you meant recreating the entire admin panel with Couch tags, then no - that is not planned for 1.4.5. Nevertheless, with the release of 1.4 we are certainly much closer to being able to accomplish this... @KK could probably comment with more authority than me on what the long-term plan is.
I would suggest if you are able to wait a little while longer, do so as 1.4.5 will have entirely new HTML, CSS, and JavaScript (using jQuery).
