Take a deep breath and mull it over. You didn't care for the way they were going together as a quilt, and now it's going to be a jigsaw puzzle to make what you've got work together in that size. So...
Since your original pattern has been reduced to pieces, why don't you set your sights on using just some of what you have now in several different projects? If you still want a big quilt, take some of the nine patches and put them into a quilt with solid squares (that you'll cut new) between each nine patch. Use the "leftovers" in smaller wall hangings, table runners, or hot pads. Nothing need go to waste.
Good luck and have fun with it!
