Sorry so late seeing this.
I do not recall them saying, but I've been planning to go back up for more coal, so I can ask then, or you can just try calling them. I've been sick...we are sick...I think from this virus, but not sure. Staying home until we're better.
So, long as it's for a 50-93 I'd say it could be done because the stove body is the same with. However, that is not to say that they may not elect to do it for other reasons. Only, Dean could answer that.
Myself, I'd like the double door option on the smaller stoves as well.
