Need some advice on a Black IPA

[ShokuPanMan]

I am trying to come up with a Black IPA recipe. Since I never brewed this style I would like a little advice.
This is for a 15L batch.

Recipe Specifications

Batch Size (fermenter): 15.00 l
Estimated OG: 1.069 SG Estimated Color: 100.7 EBC Estimated IBU: 52.2 IBUs Boil Time: 60 Minutes

Ingredients:

3.35 kg Pale Ale (Dingemans) (6.5 EBC)
0.48 kg Carafa Special III (Weyermann) (925.9 EB
0.48 kg Wheat Malt, Pale (Weyermann) (3.9 EBC)
0.24 kg Caramunich Malt (110.3 EBC)
0.24 kg Chocolate (Dingemans) (669.8 EBC)

24.69 g Cascade [7.50 %] - Boil 60.0 min
9.98 g Zeus [16.10 %] - Boil 30.0 min
23.64 g Simcoe [13.10 %] - Boil 5.0 min

20.00 g Cascade [7.50 %] - Dry Hop 5.0 Days
20.00 g Simcoe [13.10 %] - Dry Hop 5.0 Days

1.0 pkg American Ale (Wyeast Labs #1056)

Now I will do a Yeast starter to have enough yeast for the high SG to get fermented well. I was wondering if I should add some Table or Candi sugar to the boil to dry it out a bit, or even do a 90 min Boil and put the 60 min cascade in for a 90 min boil to up the IBU, or better switch it with the Zeus for bittering since it has a higher alpha acid.
What would you guys change ?

i have one that i like to do, and need to do very soon. my grain % are

marris otter pale 57.14%
Munich 20L 23.81%
Caramel/Crystal 60L 7.14%
carafaIII 4.76
Caramel/crystal 10L 4.76
Chocolate (crisp) 2.38%

my hop additions were massive and were org for a 10g batch but i scaled it to a 5g batch and kept the hops the same. turned out really good just a bit more expensive than it normally would be.

the hops i used were
ammarillo gold
casacade
columbus
simcoe.

they all went very well with the grain bill. it was a fairly big beer and was sneaky on the booze.
