HELP with recipe conversion

[brewshopmike]

A friends birthday is coming up and I'd like to brew this for him, so could someone with more experience than myself help with converting this all grain recipe from BYO into extract w/ grains?

Guinness Foreign Extra Stout clone
5 gallons/19 L, all-grain; OG = 1.078; FG = 1.019; IBU = 40; SRM = 43; ABV = 7.5%

Ingredients:

13 lbs. (5.9 kg) 2-row pale ale malt
2 lbs. 2 oz. (0.96 kg) flaked barley
1.0 lb. (0.45 kg) roasted barley (500 °L)
11.33 AAU Challenger hops (60 mins) (1.6 oz./46 g of 7% alpha acids)
Wyeast 1084 (Irish Ale) or White Labs WLP004 (Irish Ale) yeast (2 qt./2 L starter plus 0.5 qt/500 mL mini-starter)
2/3 cup corn sugar (for priming)

Closest conversion would be:

9 pounds Extra Lght DME
2 pounds Flaked Barley
1 pound Roasted Barley

The big problem here is that flaked barley needs to be mashed. Steeping it for an extract recipe only gets it wet. Consider doing a mini-mash with something like this:

6 lbs. Dry Light Extract
2.5 lbs. English 2-row Pale
1.5 lbs. Black Roasted Barley
1.5 lbs. Barley Flaked
1.5 oz. Challenger (Pellets, 7.00 %AA) boiled 60 min. Yeast : WYeast 1084 Irish Ale

7.8 lb DME.or 9.75 lb LME have the same graivty points as 13 lbs pale ale malt.

Flaked barley does not need to be gelitanized. It may be put directly in the mash.
What it does :
Flaked barley adds a rich, smooth, grainy flavor to your beer. It is high in protein and beta glucans. As a result, it will improve the body, head formation and retention of your beer. However, it can also increase the haze potential. You can use it to make English Ales and Stouts.
What it is:
These are barley grains that have been steamed and rolled to gelatinize their starches, making them accessible for conversion to sugars. Because the grain is un-malted, it does not possess the enzymes required for this conversion by itself and it must be mashed with malted grains.
So when you place your order, get some amylase enzyme for your mini mash or a couple pounds of milled ale malt and reduce your extract accordingly.

Thanks everyone... Think I'll try a mini-mash of some sort...
