I'm afraid the chances of that happening are close to nil, unless someone else takes up KOTOR tool development (which could only happen if they could get in touch with Fred, and get permission, not an easy task, unless they already had his email address), since Fred hasn't signed on for about 2 years now (though I came back after a 5 year absence, so hey, who knows?).
Right now, if you have excel, I'd recommend using tk102's Excel 2da read/write plugins. They can be found for download on the Starwarsknights.com modding tool page.
