Hello, which variation of bootstrap are you using? Did you create the joomla and VM theme by yourself or did you directly modified the original twitter bootstrap from here
http://twitter.github.com/bootstrap/. In both cases this would be worth creating a new theme, but we'd prefer if you sent us a print screen of what would you like - especially the layout and logic. The OPC themes are using various techniques to render the field names, sections, columns, logic and i can't really imagine that this all would be included in the bootstrap css. This is subject for custom work and time and we can't promise you deadline for this right now.
Best Regards,
Stan
