I wouldn't worry about the lack of air lock activity. I would just check the seal or lid maybe. I just got home to find my airlock full of pumpkin goop, and one side of my lid popped off. I would just wait until it's been a week, and then start taking hydro readings..
As far as what to do about too much spice, I would think blending two batches would work out. I would do that first, and if it's not enough then maybe have the next batch brewing so you can have it all blended for fall. Good luck, I think I over spiced mine as well. There are just so many recipe's out there with completely different spice additions. I think I prefer mine to be a little less than average. Ohh well, the next batch should be perfect, right?
