It will taste like its components, really sweet from that much caramel malt, a little bready from the munich, and with noble hops aroma. I would reduce the crystal to maybe a half pound. It won't be like a maibock because of the English yeast too. Maibock uses lager yeast, English ale yeast produces esters.
