My knee jerk reaction was NO! Don't do it! But the problem is really my OCD. If I knew I was riding with two different length crank arms, that would be all I could think about while riding. OTOH, if you try it and don't notice anything different (and it doesn't cause you any pain), then why not ride the crank that way? If indeed you have one leg a little longer (like most people supposedly), hopefully the longer leg gets the longer crank arm or you can make the problem worse!!
