I was going to make that suggestion, then I thought of something even more awesome...
Make it a double. Mash half the grains, then heat the wort back up to mashing temps, dump out the old grains, add the new grains, and remash with the wort. Sure, it still adds time to your brew day, however, at least you're doing it to replicate a cool old process rather than resigning yourself to equipment limitations. Randy Mosher talks about this in Radical Brewing and I am pretty excited at the thought of giving it a try...
If you try the double mash, I am guessing it will hurt your efficiency, so you'll probably still want a pound or two of DME to make up any deficiency there.
Otherwise, just buy a Walmart special cooler for $15 and put a SS braid in the bottom, run the tubing up over the top of the cooler and down the side. Siphon.
