Crossing roller derby — a sport of trash-talking terrors — with “Trading Spaces” — a reality show famous for its over-the-top designers — sounds like a recipe for a train wreck.

Instead, when “Trading Spaces” visited Colorado Springs back in August, the results were really quite . . . pretty.

At least that’s the description I got from Barilyn Monroe and Susie Q-T, aka Donna Chapman and Amanda Andrews, who traded spaces for the episode.

You can judge for yourself when the episode premieres at 8 p.m. Saturday on TLC (the Pikes Peak Derby Dames are holding a premiere party at Will’s Sports Pub, 424 S. Nevada Ave. — everyone’s invited).

“It was probably one of the coolest things I’ve done — other than roller derby, of course,” Chapman said.

“It was the best thing ever,” Andrews agreed.

The women live just a few blocks apart in the Briargate neighborhood and play for opposing teams in the Derby Dames league — Andrews for the Candy Snipers and Chapman for the Danger Dolls. They’re also some of the few Derby Dames who are “Trading Spaces” fans.

“Half of our team didn’t even know what it was,” Andrews said. “It’s like winning the lottery to me.”

Here’s how the show works: It takes two families, gives them each a designer, a $2,000 budget and a weekend to remake a room in the other family’s house.

Chapman and Andrews paired with teammates instead of their husbands. Andrews and Kelly “Pepper Slay” LaPage did Chapman’s living room, while Chapman and Donna “Karma Getch YA!” Cole made over Andrews’ master bedroom.

If you’re picturing some punk rock/1950s roller derby theme for the rooms, think again.

“My husband would have had a heart attack if that was the case,” Andrews said.

These roller girls don’t have tattoos, wear fishnet stockings only to derby bouts and own ordinary houses.

“If we’re not dressed up in fishnets, you’d never know,” Andrews said. “We play like real roller girls; that’s all that matters.”

As for the weekend of redecorating, it went without a hitch, although there was a little Hollywood magic to the process.

“When you watch the show you think, ‘Oh my gosh, they’re totally slaving away,’” Chapman said. “We hardly did any work.”

The teams and designers get things started, Chapman said, but a small army of production assistants is on hand to make sure everything gets finished in just two days. That being said, no one coached them on what to say or how to react to their new rooms.

“Right before the reveal, we had to wait outside and my older son came up to me shaking his head,” Chapman said. “He said, ‘Oh, Mom, it’s bad.’”

“Barilyn’s husband about died when he saw his room,” Andrews said.

When Chapman got to see it herself, though, she thought the room was pretty cool.

“I was completely shocked,” she said.

“It didn’t even look like my house.”

Since she owns a home daycare business, the white couch and pair of glass tables didn’t last long, but the red, white and green paint scheme is still up, Chapman said (see photos at springstvtalk. blogspot.com).

At Andrews’ house, things went even better. Her husband even redid their master bath to match the bedroom.

“My master bedroom was just boring before,” she said. “I absolutely love it.”

If you’d rather see the Derby Dames trading elbows than trading spaces, you can catch their next bout Nov. 3 at the City Auditorium, 221 E. Kiowa St.
