Help on Beefing up a "brown ale" Kit

Morning everyone.

I got a True Brew "brown ale" kit for christmas, and Im looking at altering it a bit to more of an American Brown Ale...

Here is whats in the kit:

1 can Dark LME
2 lbs Dark DME
Malto-Dextrin 8 oz
UK First Gold Hop Pellets. 1 oz (60 minute)

Im thinking of Adding

1 lbs. Pale Chocolate Malt
2 oz Crystal Malt

Boil 45 mins .25 East Kent Goldings leaf
boil 15 mins .25 East Kent Goldings leaf
boil 1 min 0.5 Willamette leaf


This is what im getting on a recipe creator:

Original Gravity
1.050 / 12.4° Plato
(1.045 to 1.052)

Final Gravity
1.013 / 3.3° Plato
(1.011 to 1.013)

Color
28° SRM / 56° EBC
(Dark Brown to Black)

Bitterness
24.3 IBU / 7 HBU




thoughts?

 

I always add about 1lb of flaked oats to my brown ales
