IF you could remove the wall between the triangle and the unit next to it, charge a little more, for example, of a combination of O & RR, then just an O by itself, that might work, but I think the sharp corners of a triangle by itself would be a difficult sell. Plus we always have a problem with a small room and a wide door, because the roll up ball at the top when you have the door open takes up most of the top of the unit.
