    Can this be used with a derailer to change between the front chainrings?

    A derailer might be a good idea even if only using it as a chain guide, but probably best to move it by hand. If shifting with a derailer do so carefully.
    Here is a video showing a similar modification while using a derailer. Shifting is okay for the most part but you can see it has some issue shifting at the 22 second mark.
