There is nothing wrong with this recipe as is. However, my first thought is to get rid of the wheat. I don't think it really does anything for you in this style except add some head retention and make your beer a little more cloudy. I would switch it out for either just more Maris Otter or some Vienna or light Munich.
My other thought is you might want to ferment a little warmer than 62.
