I would leave out the flaked maize. Without it you still have a 6% beer. If you want to add more alcohol, add some brown sugar, that will also give it more character and keep it more "English". If you want it darker, use 1oz of a chocolate malt. That will make it browner, roasted barley will make it redder, but 1/8oz won't really do anything. Do you have a higher AA% hop available (Northdown, Northern Brewer, Target, Challenger) for bittering (90 min)? Although I got some 2009 EKG that is 7%. I would also flip the fuggle and EKG. Use the EKG for aroma.
White labs WLP002
White Labs WLP005 (my house yeast) but use a big stater (3L for each carboy, decant and pitch slurry). Ferment at 68-70 for more fruitiness.
