The problem is that if the crank arms are the same length, when the longer leg is perfectly angled at the bottom of the pedal stroke, the shorter leg is not. There's no way to get them both set up properly (pedal under knee, leg slightly bent at bottom) if both cranks are the same length.
I agree that over an inch difference in leg length is extreme and your saddle height has to be set to suit your shorter leg. Having a longer crank on the opposite side would appear to help at the bottom of the stroke but your knee is going to be higher on that side at the top of the stroke. With your saddle already being too low for the longer leg you may be beyond the limit of your hip movement on that side.

Read this piece on my website on saddle height here. Then test the limit of your hip joint movement as described in the piece.

One suggestion I would make is to move the shoe cleat nearer the toe on your short side. With you toe pointing down at the bottom of the pedal stroke this will have the effect lengthening the foot on that side. Not a perfect set up I agree, but your riding position is always going to be a compromise. The object in your case is not a perfect riding position, but to maximize your riding experience.
