Maybe you have already considered this, but a little advice from experience on self-fabricated stoves: You might want to test it for smoke leaks well beforehand to make sure the stove does not fill the tent with smoke. A buddy built a stove for one of our trips to put in his little tent. The way he had the door open clear to the top of the stove allowed about half the smoke to come out the front at the door opening (with the door closed) rather than out the stovepipe. He also did not have a proper intake vent. The stove was so small that you could not move the fire back away from the door. It filled the tent with smoke. I did make a makeshift flange for it down over the front with a Coleman fuel can, but that didn't fully solve the problem. It made the stove considerably less useful. I would recommend studying available stoves for designs.
That is a nice looking tent. Will you have extra sleeping or gear storage tents? With cots up inside, and the need for space around a stove, a tent can shrink down smaller. You will need the stove away from the tent walls/ When you have it set up this summer it might be good to layout what will be inside it to check floor and movement space.
