Widgets with sidebar/page plugins

I’m setting up a WordPress site for a resource site (I’m not a WP newbie, don’t worry), and I was wondering how we could make existing plugins work with the new widgets.

I’m using a “hide pages” sidebar plugin, where you can manually pick which pages show up in the sidebar. In that, you replace wp_list_pages() with sps_list_pages(). However, because the widgets plugin totally modifies the coding of the sidebar, I can’t for the life of me find anywhere to replace this code. I found the “pages” section of plugins/widgets/widgets.php, but it uses totally different coding to achieve the same thing.

Is there any way they can work together? Or do I have to choose one or the other?
