Wheat IPA Recipe - Any suggestions?

I'm trying to come up with a recipe for a Wheat IPA. I'm using some ingredients that I already have for a base Wheat beer but I want to try something different with a little hoppy character.

Here's what I'm thinking so far:

8oz Carapils [in stock]
8oz Crystal 20 [in stock]
6lbs Wheat LME [in stock]

1oz Simcoe @ 60min
1oz Tettnang @ 30min [in stock]
1oz Hersbrucker @ 5min [in stock]
1oz Cascade @ 2min

WLP300 Hefeweizen Yeast [in stock]

1oz Cascade in Secondary (Dry Hop 1-2 weeks)

I'm open to changing the addition times and even the hops. I'd like to use what I have in stock if possible. Thought the Crystal malt would add some sweetness to offset the bitterness from the hop addition, not sure if I should use all 8oz or less, or if I should use a different malt altogether. Thinking the Simcoe/Cascades could add some extra citrus notes (always good with Wheat) and raise the IBU's.

Let me know if you have any suggestions. Thanks all!

I've never brewed an IPA with 50% or more wheat. Lagunitas A Little Sumpin' Sumpin' is about 50% wheat. They have a clone recipe for that beer on Jamil's "Can You Brew It" podcast.

For an extract version, I would use half Extra Light DME and half wheat DME and nix the carapils since it is already in extract. The crystal malt issue is more about preference. I prefer 0-5% myself in an IPA. I do however like to add sugar to my IPAs. Honey would be more fitting here at about 10-15%. I like the idea of Honey-wheat IPAs.

You don't need to bitter with Simcoe. I would bitter with my least favorite hop that I have on hand and make-up for the addition amounts as it pertains to aa%.

For a hop schedule, I like 1/2 oz at 60, 1/2 oz at 30, then 5-6 oz more hops split between 15, 10, 5, 0 and DH.

I was looking at some clones for Lagunitas A Little Sumpin' Sumpin' and also Three Floyds Gumballhead. The latter looks closest to what I was thinking.

They're using some 2 Row, White Wheat, and Belgian Cara-20 with 5lbs Wheat DME. One person couldn't get the DME so they used 6lbs LME instead, so it could work for what I have in stock. They're also using Amarillo hops instead of Cascade or Simcoe.

Think I'll pickup the 2 Row, and 3-4 oz of Amarillo, and might stick with the Crystal 20 instead of the Belgian (don't want it overly sweet). I'll use the Tettnang and Hersbrucker @ 60/45, and then use the Amarillo for the rest of the schedule .50 oz @ 30, 15, 10, 0, DH.

I'm starting to think I might need to use a different yeast though. Not sure the WLP300 is right for this beer. Might go with the Safale-05 they're using for the GBH.

That sounds good. Instead of 2-row, use some Extra Light DME. Skip the wheat since you're using wheat DME. I would say 3-5% total cara/crys 20 will do. Cara and crystal malts are the same thing. The only difference is the country of origin.

Or you could go the partial mash route with 2-row and wheat malt...though I would know what I'm doing before I start buying ingredients and winging a recipe.

I would personally use an English yeast for this beer.
