So I gave it a try today and it worked out better than I had hoped.
And I got some pics. Full directory:

I grabbed some bad parts from the scrap bin and a piece of 308 filler rod. First, three parts that have a hexagon profile, three welds holding them together. Welds were polished with a red scotchbright wheel.

Then one of the hex parts and another part:

Then I tried some fillet welds on crossed pieces:

Some similar parts and did a butt weld without filler:

(sorry about the over exposure) Better pic:

Then I took some larger pieces and ran a butt weld:

about the size on this last one, don't know how that happened.
I had put my camera away, and then thought to use the larger chunks to make a fillet weld and see how it busts with a hammer.
It broke through the bead, and showed incomplete penetration at the root, as expected.
When making the welds, I was sort of brazing with the filler, trying not to dilute the puddle with base metal.
Not for anything structural for sure. But for "Objets d'art", works just fine.
