That's tough. Atlas Snap-Switches have a continuous 18" curve. At least some #4s have a minimum 15" radius, but are straight beyond that. I doubt any American company makes a turnout with a continuous 15" diverging route. Some European manufacturers probably do.
You might find a tight-radius switch in a box of old track. I think Fleischman made them and possibly Hornby-Dublo. But these go back to the 60s and the flangeways are probably a bit wide.
a standard #4 Atlas Custom line would probably be about 18 inch radius, but that would probably make a nice transition curve into a 15 inch. If your locomotives and rolling stock is small enough, you might be able to use flex track and reduce the radius to 12-14 inches in the center of the curve to make it fit the door if necessary. Most equipment will handle a short section of a tighter radius than they are designed to operate on continuously.
