Integrate Linkit with IMCE

The latest version is working well for me with CKEditor (standalone), but I've gotten to thinking. It helped me to edit the plugin.js code to offer my users a more descriptive tool-tip label for Linkit ("Link to an internal page") to distinguish it from the existing Image and Link buttons (though I would like to find a way to change the tooltip for Link to "Link to URL or file" to complement what I did with Linkit.

Is there any way to further simplify toolbars by integrating the Linkit functionality into the IMCE-based link/browse popup dialog? Ideally, I would like my users to be able to use the same button to insert links whether to internal nodes/views/users, uploaded files, or external URLs, though it wouldn't have to be through the same text field within that dialog. For example, that Link popup has a field for URLs with a separate button to browse the file system.
