Cooktop Accessories for RMH such as Disk Plow Grill or Teppanyaki grill?

Good Day,
New to this game and I have been testing materials and think I have watched every video out there and ordering the book. I want to build a RMH in my small hunting cabin with a bench on one side and kitchen counter on other.
Wondering if a new weight supporting top was welded on top and set up for a Teppanyaki grill or Disk Plow grill or Wok. I have seen the Pizza oven and boiling water but would it heat up a 1" solid metal flat grill top that over laps the top of barrel.
And or would it be to hot? Thought of welding a large bolt on top and having grills tapped for it making adjusting the heat by spinning the top to raise. I understand how I would incorporate into a counter with the high heat,
but not knowing how hot or side effect of doing this on the stove's burning efficiency. Any input?

Mr. A : Fast Answer Yes, but it depends ! Some people do use the top of the barrel as a direct cooking surface, it can be seasoned just like a Cast Iron pan !

The book will, when you get it describe to you a near ideal working gap between the Very Top of the Heat Riser and the underside of the Barrel top as 1.5'' -2''
for a 6'' system and 2'' - 2''+ for an 8'' system, by going just a little bit shy of those measurements, and carefully feeding your fire, you can make the top of
your otherwise Conventionally built Rocket Mass Heater, RMH, Glow Cherry Red !

One of the First Accessories people make for their RMH is a big bowl made from multiple layers of aluminum Foil, very handy for baking, and useful for proofing
bread dough ! Pizza stones also work well at this location. Good Luck, am I am sure we all would like to see plans and pictures of your build as it advances !
