Only reason I tend to think it will work is, if the size of that duct is "close" to right, the furnace will compensate. Once the flex duct with it's length bends and kinks is added, the furnace can't overcome that added restriction.
You can't mess things up by shortening the return duct. You can only mess it up by restricting it. The only thing you might get by shortening the duct is some whistling or vibration through the return vent. If it does this just take a pair of needle nose plyers and open the louvers a bit.

Awesome. This is the answer I was looking for. I will take a closer look at it on Thursday when I get the test results back!
