I agree with inhousebrew, do something simple and then add from there. I'm actually going back to the drawing board and doing a single hopped ESB with all Northdown and plan to add/sub hops afterwards. However, all EKG is always a great hop schedule for an English ale.
Despite my advice for going simple to start, here are some comments on your latest revision. I did a lot of research on Brewer's Gold hops about a month ago (supposed to be very similar to Bullion), and found that most people suggested a longer boil for them. They said they didn't like them late in the boil and that the longer you boiled them the more they liked them. I'm torn between suggesting moving the Bullion addition back in the boil or saying try it and report back
. Also, I personally wouldn't "waste" the EKGs for a 60min addition they are just too good for that, if your mixing different hops for each addition I would use something like Target or Challenger and save the EKGs for later in the boil (unless you are going for something specific with that addition).
Good luck on the brew day.
