How to deal with this area of drip rail?

So back at the garage today, and I went looking through the parts we got with the car. I have driprail trim, so it was part of the car originally. I think I want to leave it off. I think my game of attach is to align and weld those two sections together. The gap on my car isn't as big as in the picture I posted. I could probably just weld it up without making the tiny little patch panel to fill the gap. I've got plenty of time to think on it.
You should have no problem welding that gap. like you said take your time.
