Finally got my Princess Insert completed, with an insulated stainless liner, roxul at the top and bottom of the flue, and a block-off plate above the stove. Hopefully I did everything right, I hate doing stuff twice.
I got a 5" tall rectangle bent up buy a local metal shop and bolted it to the top panel because my fireplace is taller than most. I'm having a bit of trouble sourcing longer pieces of the aluminum trim that goes around the surround, so it stops 5" short of the hearth, but I don't think it looks too terrible. I'll probably eventually get some more trim and fix that.
The "black" high-temp paint I got to repaint the surround after modifying it turned out to be closer to grey, but it doesn't look bad in person.
