At this time, that is not possible with the way the plugin is coded. Although you can change the "Send A Message" text with a filter, and even totally remove it with the filter (which will effectively remove the link), there is not any filter in place that would allow you to change the link for the name to something else (the name is used to link to the member's bio/post page, if you have that option enabled).
Please feel free to add that to the feature requests on my plugins site for future consideration.
