Mashing in spare cooler, transfer to cooler with manifold afterwards?

[MarkInBuffalo]

Hello all. I'm brewing Yooper's 60 min clone next week and trying to figure out how I can achieve a ten gallon batch. I mash in a Home Depot 10 gal orange cooler with a copper manifold and I've found that it pretty much maxes out around 22-23 lbs of grain. My total bill for ten gallons of this is about 27 pounds. My question is this: I have another Home Depot ten gal cooler that is not setup with a manifold yet, does anyone see a problem with me mashing half of the batch in each cooler, draining the cooler with the manifold into the pot, emptying cooler, pouring content of the other cooler into tho manifold cooler, and draining again?

Sub some of grain ofr extract. Run your figures again with 1/4 gallon (3.25 lbs? Maybe?) of LME. It'll work. I've done it with great results.
