I don't get why you would want to mix VSD and WP.
I'm all for VSD, especially on SDrive with a Stream. Very easy to manage

But both WP and VSD/SDrive provide a full website with blog, so no need to cobble them together.
After trying to help a client get to grips with a WP site (commissioned by her organization's home office) – 2 weeks of trying to make a custom template work, every little thing was a pain in the @$$. I told her if we could ditch the WP site, she could have a new site, done exactly how she wanted in a few hours. I made the site in VSD, saved a copy on a jump-drive, bought VSD to put on her computer and voila! The client is familiar with Photoshop, so learning to use VSD was easy for her.
As for those clients (except for the one above) who said they wanted to be able to manage their own sites... well, none have ever gone near their sites.
