Has anyone successfully integrated Marketpress Ecommerce with Elegant Themes 'Boutique' th

Hi,
I'm trying to set up a multivendor market using the Marketpress Ecommerce plugin. The look and feel of the Elegant Themes 'Boutique' ecommerce theme is pretty much spot on for my brand, but I know that Elegant Themes do not specifically support Marketpress for this theme. Has anyone successfully used 'Boutique' in this way before, and if so, would you be willing to share how you managed the get it working? If not, can anyone suggest some other beautiful themes that could do the job...I'm not a big fan of the ones offered on this site.
Thanks in advance.
