Pale Ale with 1/2 Kit and 1/2 All-Grain for 10gal

[spin]

I have recently started to brew all-grain but I still have a Coopers Pale Ale Kit with a can of Coopers Light LME in my fridge.
I have the 10 gallon brewery from Hop & Grape which I'd like to make a 10 gallon brew with. I've only done one 5 gallon brew so far with it.
Would it be worth it to try and make a brew from the kit and LME and add this to a 5 gallon all-grain pale ale recipe to make 10 gallons. Silly idea??
If I did this, would I just add the cans of malt to the end of the boil and add extra cold water to 10 gallons. I suppose this would be good for cooling the wort aswel.
I want to try a 10 gallon brew but don't really fancy having to mash twice so this would be ideal.
I would buy some new yeast suitable for a pale ale as I can no longer get hold of the Coopers Pale Ale stubbies to reculture the yeast. Then I could keep the kit yeast for another brew as I believe Coopers use S-04 or similar which is good for some other brews I have on my to-do list.

I'm confuzzled.... :wha:

I might be missing something here but if you have the 10 gallon brewery from hop and grape why would you need to mash twice? personally myself i would never mix a kit and an all grain but for no reason other than it would at least reduce the quality of the all grain brew.

The reason I'd need to mash twice is that when I did a five gallon batch it used my mash tun to the brim. So I'd need to mash twice I think for a10 galon brew. My boiler and fermentor easilly hold 10 gallons though.

I was just thinking that maybe as a kit it wouldn't be so good, but mixed with an all-grain recipe I would get a much nicer brew rather than doing the kit separately just for the sake of doing it. If that makes any sense.

i used a youngs bitter kit as part of a all graing brew to make an imperial stout, but i stuck to a 25 ltr brew. it turned out quite nice.

Thanks for the replies chaps !!
I think I'll have to just fly by the seat of my pants and give it a try. I'm a little worried incase I end up with 10 gallons of rubbish. But I'll just have to try it and see how it turns out. Going from past experience, the beers I wasn't expecting much of have usually turned out pretty good.
