Controlling position of the link to the original post

Is there anyway to control the position of the link to the original post that appears after the excerpt? I add commentary to the excerpt and I'd like the link to be between the excerpt and my commentary instead of the bottom of the page.

I use 60 word excerpts so what would be perfect is if the plugin could count 60 words, add a break and then add the external link.

I realize there is nothing built-in that can do this, my question to the developer is whether or not this would constitute a major mod that I'd need to hire someone to complete.
