I'd cut the 6lb pilsen LME to 3lbs,& sub in about 3.5 lbs of plain extra light DME. Use half the DME in the boil. I do 3G boils currently. Not to mention,you have no Bittering addition. So half ounce of the Summit hops at 60 minutes,since they're 18.5%AA. You're 1st two hop additions stay @ 20 minutes,the 2nd two @ 12 minutes,& the last two at 5 minutes. That'll give you some bittering,& better flavor with some aroma at the end.
Add the remaining DME @ flame out,along with all the LME. That'll give lighter color & cleaner flavor.
