That would be a great solution as long as you have all that wood available to you. I like barrel stoves myself. Very inexpensive and super fast heat up capabilities. As long as you have enough space around them they're very safe. In your case I'd run stove pipe straight up through the roof. It Should go to two feet above the peak so you don't get down drafts. With your ceiling height this would work well to keep it warmer down at floor level. Oh yeah, I wouldn't do any painting when you got the stove cooking. I remember going out in the garage one Sunday morning in my tee shirt with a bunch of newspapers in my hand, the temp was 0 degrees. I crumpled up the papers and stuffed them in the stove, lit a match and didn't come back inside for four hours. Instant heat!
