Recipe Critique: Abita Amber Clone (sort of)

I'm making an amber ale for a friend who likes Abita Amber. According to the site it is 15 srm, 17 IBU, and 4.9% ABV. It's also, a lager, which I'm going to pretend I don't know about, as I'm using Pacman. Basically, I'm going for a dark, malty, light bodied amber. Here is my recipe so far, what do you think?

11 gallon batch
1.055
SRM 15
IBU 17
Pacman Yeast @60 degrees

15 lb. American 2-row
2 lb. American Munich
1 lb. American victory
2 lb. American crystal 40L
14 oz. American crystal 120L
1 lb. 8 oz. Dextrine malt (Cara-Pils)
2 oz. American chocolate

.5 oz. Magnum (12% AA, 45 min.)
1 oz. Crystal (3.3% AA, 20 min.)
.5 oz. Perle (8% AA, 20 min.)
.5 oz. Perle (8% AA, 5 min.)

^^bump^^^^

Abita's website can clue you in on the hop profile especially,.. among other things.:

Amber is a Munich style lager brewed with crystal malt and Perle hops. It has a smooth, malty, slightly caramel flavor and a rich amber color. Abita Amber was the first beer offered by the brewery and continues to be our leading seller. Amber is Abita’s most versatile beer for pairing with food. It has been voted "best beer" in numerous New Orleans reader polls and is used frequently in recipes of great Louisiana chefs.

Because of its smooth, malty flavor, try it with smoked sausages, Louisiana boudin, or even with caviar. It’s great with crawfish and Cajun food. You might also enjoy it paired with a spicy gumbo or tomato-based pasta sauce. It goes well also with fried catfish dipped in a tart, lemony tartar sauce. Parmesan, Pecorino and Romano cheeses are good pairings with Abita Amber.

Here is what I came up with in BeerSmith after looking at their site:

Amount Item Type % or IBU
7.75 lb Pale Malt (2 Row) UK (3.0 SRM) Grain 88.57 %
1.00 lb Caramel/Crystal Malt -120L (120.0 SRM) Grain 11.43 %
0.50 oz Pearle [8.00 %] (60 min) Hops 15.0 IBU
0.25 oz Pearle [8.00 %] (10 min) Hops 2.7 IBU
1 Pkgs American Ale (Wyeast Labs #1056) <--instead of munich lager


All that comes out to almost exactly what their website denotes on abv, color, and ibu's.

Est Original Gravity: 1.047 SG
Est Final Gravity: 1.011 SG Measured Final Gravity: 1.005 SG
Estimated Alcohol by Vol: 4.61 %
Bitterness: 17.7 IBU
Est Color: 14.9 SRM


Can it really be that easy? I'd like a critique of what I came up with.
