I'm not sure whether it's called "theme integration" or "theme conversion".
How to do this?
I wasn't able to find any tutorials.

You need to do two separate themes to achieve this. One for vB that uses a similar layout and is integrated within the vB variables, layout, etc. and uses the WP CSS (variables hooked of course). But there's no plug and play option for this.

I'd suggest to look for the header integration, you could achieve that by calling the global.php from WP but still, isn't a full integration and it would be a half solution.
