I think no. The architectures of these systems are different. So, I do that in such a way:
1) To install a WP skin locally or on a website
2) To create a couple of entries and comments, to create menu items
3) To save as an HTML website
4) To open the saved HTML file in a text editor and edit the HTML code
So, no specific operations.
P.S. As an example, you can see this Subdreamer skin
http://www.sddepot.com/plugins/p13_download_manager/images/78.jpg
and the same skin operating in ExpressionEngine

or compare this Subdreamer skin
http://www.sddepot.com/plugins/p13_download_manager/images/68.jpg
with
http://tulks.valsts.lv/site/
I don’t think that WP skins are nice. So I use skins from other systems.
P.P.S. I hope I can reply in ‘Pre-Sales Questions’ because I do such modifications for myself often. (a hobby, I’m not a web designer)
