I'm thinking this might go well on the PBC. Perhaps in a cast iron skillet atop the cooking grate? (Which would provide juice for a reduction sauce). I'll give it a try in the next couple of days and report back

Don I have been experimenting with my PBC during turkey season....And - here is something to consider: any meat will roast better if not actually in the pan - but exposed to the hot air currents and any smoke desired.
SO - if you have 2 grates for your PBC ( I am pretty sure a Weber style grate will work...Lowe's HD, or similar...better yet - order the new split grate from PBC!) - place one grate in the PBC - then place a pan ( disposable foil pans can be cut and shaped to your needs...) in the center on that grate. Now - using 3 paver bricks, placed at the 10 o'clock, 2 o'clock, and 6 o'clock positions on the rim of the grate. Now- place a second grate on top. Set he roast directly above the drip pan - to catch drippings ( good to add aromatics, broth, beer, wine or whatever you like for some steaming flavors...)
If you can't find pavers to fit - use any temperature save materials - including tightly balled up aluminum foil to create the correct size "spacers" you need for supporting the second ( or top) rack.
Wish I had some pictures for you. I have been busier than usual this season. The wife broke her foot in 3 places ( she kicked me where I carry my wallet
- just kidding..)
