A few new developments in this jacket saga have come up.

After trying on everything with the kilt and sporran, I realized that the pleating in the back has changed the hang of the front of the jacket enough that the raised curve to tapered hem line is not needed. In fact, it would not work at all. Instead, a simple cutaway curve just below the second button will work fine. The jacket hangs open wide enough that it doesn't interfere with the sporran, however, I get the feeling that it would all look better with a third button between the two that are on there already. The hang isn't perfect in the front, but I think it will work.

I have started a new thread on this, but as a final note there is this. The slit pockets will work out on this jacket because I have removed the pocket flaps, and will attach them to the outside of the jacket and the bottom lip of the slit pockets to make a kind of cuff for the pocket on the outside. Because the cutaway taper is not needed anymore, the pockets have a bit more room.

I think that's it.
