Can I use a ColorLabs theme with MakretPress?

We want to use ColorLabs 'Opulence' theme with MarketPress. ColorLabs documentation says it works with WP-ecommerce, Jigoshop or WooCommerce.

I realize we could pick a non-ecommerce theme and add MarketPress but everyone likes the Opulence theme. How do I avoid duelling ecom solutions?
