I would tend towards extending the elements you have already added. Keeping the rhythm and masses. The top element could be stacked and lap the lower mass versus being a cut line like I show here.
Breaking up the mass I think is a good thing as compared to the thumbnail I show below.

Consider the source and its free worth exactly what you are paying for itMany thanks for the time & thought you put into your posts, Karl.
The main problem with what you propose, is that I cannot get under the existing cap to weld/fill/bond that forward inner area, so reshaping that pretty much is a no-no. There is the molding that covers that inner curve. The other issue is I want the parting line created by the rail cap to visibly end within the D post when viewed from 3/4 angle - I don't like the way it appears to run off the back of the post, I really feel it needs to have a punctuation with the post.

my intention, maybe not so clear in my sketch, was to echo the corner crease where the 1/4 ends at the taillamp. My addition would need to come forward another 1/2" or so, and drop around equal depth to the rail side, then I think it would be evident when viewed as above
Yes it is a way to give yourself extra material you can grind a consistent radius to transition from the ‘vertical’ to the horizontal. Brazing works very nicely for this as it is lower temp and easier to work. Trying to make a consistent forms from scraps can be difficult. It’s just a thought.Not really following - use rod to make the form & butt weld sheet to that? I wouldn't want to do it that way, I don't think. Or is that to get the bevel on the top edge? I have remnants of panel edges I will use to refine the transitions from the added section to the existing. Will be more work, but should make it less rudimentary where it joins the outer panel forward edge under the rail
