Really liked the marble and gold on this so figured it would make a good variant 
In the Gotham Gallery, a shaft of moonlight fell on the willowy figure of the Venus De Chirico upon its plinth, glinting off its breasts of black marble inlaid with veins of gold. On loan from the Metropolis Museum of Fine Art, it depicted the goddess Aphrodite, and was a priceless sculpture.
Broken glass showered down from the skylight, followed swiftly by a coil of rope, down which descended the lithe, latex-clad figure of Selina Kyle. She landed nimbly before the statue, her figure as comely as the goddess herself. Her eyes glittered with greed.
“Stop right where you are, Catwoman,” snarled a commanding voice.
She gasped. The statue was breath-taking, voluptuous… but it wasn’t the Venus. For starters, this one had arms, and the shape of the batlike ears upon its head was unmistakably that of her long-time foe. Not to mention the utility belt tastefully blended into the artwork.
“Batman?!”
The statue barked a smug laugh. “I knew you wouldn’t be able to resist stealing the Venus. So I decided to lie in wait for you tonight. I’m afraid the only thing you’ll be acquiring tonight is a double helping of justice. Hyah!”
At his battle cry, Catwoman sank into a coiled stance, prepared for combat. The statue wobbled on its plinth. Nothing happened.
“Isn’t this the part where you break out and defeat me, Batman?” Selena asked slyly, a smile of delight twisting her lips. With catlike caution, she approached.
“Hyah!... Hnugh!.... Rrrghah!” came Batman’s grunts, the statue rocking a little less with each one.
Tentatively she touched it. When a meaty fist failed to smash through the dark marble from within, she grew more confident, stroking its sensuous hips and belly. Beneath her fingertips she sensed the desperate struggle of the human core inside the stone skin.
“What’s wrong, Batman? Trapped?”
Her mocking laughter rang in his ears. She could hazard a guess at what had happened, as the Caped Crusader continued to writh against his own disguise. At 200 lbs of hardened muscle, his brutish physique would never have fit the proportions of Aphrodite. But like this...
“How long have you been planning this?" she wondered. "You must have been starving yourself for months for this disguise to work, and I dare say you’ve not visited a gym during that time either. You’re weaker than you’ve ever been, certainly weaker than you anticipated before you coated yourself in stone. Now you lack the strength to escape. Oh, this is too perfect.”
The desperate, muffled grunting turned to laboured panting as his wasted strength abandoned him.
“I feel like the cat that got the cream,” she purred, tracing the lines of his voluptuous, fecund breasts. “As the Venus, you were worth a fortune. As Batman, there’s no end to what the crime families will pay to own you. We’ll auction you off, and soon you’ll be a part of their collections, or perhaps decorating the brothel of the Iceberg Lounge.” She giggled. "Maybe they'll install a water feature."
A helicopter hovered over the gallery and cast down a second rope through the hole in the skylight. Ignoring his pleas for mercy, she lassoed it beneath his breasts, the rope lifting him skyward from the plinth, and away to his fate.
