Well, you could go back and buy...
66 lbs Pale Malt(2-row)
14 lbs Munich Malt
7 lbs Crystal 40L
3 lbs Victory Malt
...and add it to what you already have. Mix it all up as thoroughly and evenly as possible and then divide it into 8 equal portions. Then you can brew the Common to the correct recipe eight times.
Seriously, though, I don't have any idea.
