Nope. Even if the board connectors match (go over the tear-downs that iFixit has for both models), video/graphic controllers on the board would be completely different for Retina vs. non-Retina. AND since the screen and glass are fused, the screen assemblies are very expensive. One way to go about it is to sell your iMac and purchase a Retina iMac. Less hassle and guessing and no risk of breaking anything "in case it was feasible."
