Ty will battle for the spotlight with the previously announced “The Revolution” hosts Tim Gunn — star and notable “mentor” of Lifetime’s “Project Runway,” and fitness and nutrition celebrity Harley Pasternak, who is maybe best known for the 5-Factor Fitness diet.

The addition of Ty is not entirely surprising, given his ABC connections -- and “The Revolution” is being produced by the same company that produces the new weight-loss” edition of ABC’s “Extreme Makeover.”

It’s unclear who’s scratching whose back here: Ty’s “Extreme Makeover: Home Edition” is no longer the ratings force it once was. This past Sunday, for instance, it attracted about 7 million viewers — finishing well behind NBC’s Sunday football game (18 million viewers) and CBS’s “The Amazing Race” (10.8 million) — and finished in fourth place among English language broadcast networks among the 18-49 year old viewers ABC targets, also behind Fox’s Sunday comedies.

So how does the goofy/quirky “Trading Spaces” carpenter turned Disney design-guru-cum-product-pitcher fit into a show, the hook of which is that each week some woman’s five month weight-loss journey will time-lapse in just five days, with daily results, and her final transformation revealed on Friday?

According to Brian Frons, head of daytime TV at Disney/ABC Television Group, the new daily show will ambitiously (and, we might add, Oprah-esquely) attempt to “help viewers complete transformations in all areas of their lives, including family, physical, and emotional well-being, fashion, home design, personal finance, food, jobs and more.”

Ty’s empire already includes Ty Pennington Impressions with Westminster Fabrics, the Signature Home Furnishings by Ty Pennington line, a seasonal home décor line carried at Sears called Ty Pennington Style, and a flooring line called Ty Pennington Collection for Lumber Liquidators, available in stores and online nationwide.
