16 in the front would be a bit much and hard to package. 14 should be fine though... i know i have room for them with 6" of lift. your rear rates are a bit stiff, you'll be riding really high unless your jeep is way heavier than mine. i have 14" 200lb upper springs and 16"300lb lower springs plus a 4" keeper spring on top. i'm at about 7" uptravel and 9" droop in the rear.
I do have a set of 16" 200lb king springs if you want to borrow or buy them to play with. i used them for setup so they're definitely scratched but never driven on.
