If you're looking for a cheap fix, you could get a blank round metal electrical box cover, cut a 2.5" hole in the center (or whatever the diameter of the draft tower) and paint it with some type of chrome or silver paint. This would cover the large hole.

Then you could put a draft tower flange over the wider plate you made. One that is meant to fit the tower, and would cover any unevenness in the hole in the lower plate.

You could also order a stainless steel disc like this to make the lower ring. A little more expensive but might look nicer than the electrical box cover. Especially if you could polish it to a shiny chrome-like finish.

Or if you have a welding/fabrication shop nearby, see if it's something they could whip up for you.
