I believe I'll go for that bowl of kash, now. I went back and re-read all the stuff that Apil and Leah and Diantha had written about Akitu. Then I tried to rework the puzzle. After much serious head-scratching, I finally broke 50%. I like my puzzles to be challenging, but this was a bit more than I bargained for. Great mental exercise!

I'm going to grab my plaque and run like heck for the KB. You have given me the Grandmother of all headaches. Thanks for all the fun!
