I'm looking over the proposed recipe above. I really can't help much with the hop-profile, but I can help with in a couple areas:
100IBU hopshot @60 minutes (Use about 10-15ml at this addition. That will get you close to 100IBU. That's equivilent to 20-30AAU or 1.5-2oz of a 15% hop)
5 minute addition- 1 ounce of Simcoe
2 min addition- 0.5 Amarillo, 0.25 each of Centennial, Columbus, Nugget, Chinook
(While not completely out of the question, I doubt they climb up a ladder to add hops at 5min, 2min, and again in the whirlpool. I would recommend un-complicating this. Assuming roughly 3oz of hops added to the kettle late (5-15min), and another 3oz of hops that are whirlpooled (possibly added at flameout depending on how their brew house is setup. That is 1lb/bbl for each addition. You've got 8.5oz between the two additions, I would assume a little less
Whirlpool (30 minutes from 180-160)- 3 ounces simcoe, 1 ounce Amarillo, 0.5 each of Centennial, Columbus, Nugget, Chinook
(I added your late kettle additions, and your whirlpool additions together, and it broke down to: 4oz Simcoe, 1.5oz Amarillo, and .75oz ea of Centennial/CTZ/Nugget/Chinook. That's 47%, 18%, and 8.5%x4(35% combined) respectively. If we keep those ratios the same, but target 6oz total, you get 3oz Simcoe, 1oz Amarillo .5oz ea Centennial/CTZ/Nugget/Chinook. So basically, take your Whirlpool addition, split it in two. Add half with somewhere between 5 and 15min left, and add the other half at flamout (to then be whirlpooled for 20min), or however you want to replicate their whirlpool addition. )
