Currently, there is no property that will change the alignment of the check box. You can submit a feature request for this. You can do this with a creation filter. If you have never used a creation filter before, the following help article gives a brief overview:

In your creation filter instance, you would put your logic in the AfterCreateChildElements. When the parent passed into the method is an instance of GlyphToolUIElement, you would rearrange the child element within by setting their Rect properties. There should be two child elements. One of type ImageAndTextUIElementEx (to display the image and text of the tool), and the other of type CheckIndicatorUIElement (for a check box) or OptionButtonIndicatorUIElement (for a radio button). Also, it appears that the GlyphToolUIElement is internal, which might be a bug. But you can easily work around this by checking that the parent.GetType().Name is equal to "GlyphToolUIElement".
