They might build more comb from the bottom of the frame before the honey is eaten up. You may be able to minimize this by placing the short frames as the outside frames in the box.
If I was faced with this situation, I'd cut a board suitable to fill the space below the medium frame, and glue it to the bottom of the bottom bar. If you put some glue on both wood surfaces, then place a piece of paper in between the two "wet" glue surfaces, there will be a fairly weak bond. You could later remove the spacer when you want to return the frame to regular service.
But whether this is a practical plan for you depends on whether you already have suitable tools available. This is also a good demonstration of the value of having all one size frame.
