Since you ask...... I think you'll be OK. Something looks off though. The original arch horizontal surface looks convex relative to the top surface of the sill. And it looks much wider. You could possible slit that arced surface and tuck it in and weld it shut if you think that is OK. Think about where the door is when shut and how the door seal will fit over the lip and compress against the door panel. If the sill and dogleg will line up, then I'd go with it. The gap under the door looks wider than thru the dogleg arc. Maybe a optical illusion. I think ccrunner needed to open the door gap on his P1800 build. He ground it down then welded the edges back together. You could just add a weld bead to tighten up the bottom door gap.
When you get to the other side, think about leaving about 1/2inch of the outer surface around the original arch to preserve the shape
and gap around the door.
I see you didn’t have to cut into you jam with that dogleg. Nice, mine was rust. Don’t take that dogleg for 100%. It’s just clamped there. There is plenty of adjustment. Although I think it may end up with a narrower gap than the bottom. I never thought of welding on the bottom of the door to make that gap narrow that’s a good idea.
The arc of the new to old is slightly off but I think I can tack it and tap it as I go to blend it together. These will be all Tig welded.
