Double loop Layout help

I have a 060 and 048 Fastrack double loop set up that I use for around the tree. With Christmas in the rear view, I am thinking about tossing the board in the spare bedroom and adding to the center of it until it's time to set up for Christmas again. I have attached the SCARM file of what I currently have. I have tried to figure out a layout that makes sense, but I have been unsuccessful. I have the following track supply to work with. I have four 036 CC switches(2LT, 2RT), a 072 CC wye, a set of bumpers, an operating track, elevated trestle, graduated trestle, several 10" straights, several 036 curves, a complete loop of 072 curves, a half a loop of 060, several 1 3/4", 1 3/8", and 5" straights, a 90* crossover, and several 036 quarter curves.
