looks mighty tasty.
are you going to make a yeast starter? very important for such a high gravity brew.
IMHO, i would sub in a little victory malt for the wheat. personally i'm not a fan of wheat in my DIPAs, but if you like it, go for it. victory malt adds a fuller mouthfeel and a richer malt character, almost biscuity if you add above five or six percent. avery maharaja is a good example of this. also, are you using pellet hops? you will probably lose a lot of wort in your boil kettle with that many hops. personally, i would up your batch size to 5.5 gallons or 6.0 to actually get five gallons in your fermenter.
looks awesome, i love a good DIPA, and your recipe should give ya that. cheers.
