cant really figure out what you mean, but rather than a stove, why not get a surround victorian style and do brick work around the actuall opening, i.e back and sides of chimey opening, and then place a nice ornate grate on the heart, in the opening, if you know what i mean. was fire place shopping myself recently and know exactly what i mean in my head! Issues with heat loss from such a wide opening?? check out this website, 2 pictures on the right illustrate what i mean! [broken link removed]
