I had to move a clip on a guys car before but it was the cut and butt installation. Here are some pics of what I did.
Here was the issue with who ever done the original clip. 
 
Here's a close up pic of how it was tied it together may give you some ideas. I cut the cut lose and removed enough metal to make it center and butted it again.  The area final weld it was boxed on both sides and the diamond shaped plates reinforced over the vertical welded area. I don't believe in leaving vertical welds with no reinforcement. It could be over kill but its safer at least in my head.lol Its just one of those things I do and other may not agree.
