My plan is to make mine just like yours, but to use threaded pieces to conect the 4" piece to the elbow.
The 3/4" piece is hidden between the elbow and the threaded fitting. You can avoid it if you use what is called a "street elbow" (yo yo yo). The street elbow has one side on it that fits INTO another fitting, instead of OVER a pipe. However, if you use the street ell then you won't be able to flare it out - because the copper too hard.
Here, I found a old pic showing a copper scrubbie on the part in question:
