Lying in bed this morning reliving my previous evenings work, something clicked in my head that I got my arithmetic wrong. Now it's too late to edit! 

So current chassis & planned body = 86g. Add a couple of g for the lighting kit and I will be at 88g, not 90g. So swapping to a slot.it pod would bring it down to 85.5g, and if I change from blutac to a sticky foam pad to fix the chip in place, I should be right on the button!
