Well you could do a spring over (SOA) but that will net you 6-7" of lift. I would say your two best options are either a nice soft add-a-leaf or new springs from ESPO with 3" added in. Really research the add-a-leafs....most of them make for a super stiff ride.
DO NOT go with longer front shackles....funky, dangerous steering probs will arise. To get a 3" lift out of shackles you would need to MAKE 6" LONGER THAN STOCK shackles......see where I'm going here = BAD IDEA.
A note on your rear shackle flip:
If you only flip the rear Shackle two things will happen. 1.) Your Pinion angle will change significantly...that means bad vibrations and increased parts wear. 2.) You will move the centerline of axel forward, possibly causing some tire to fender contact @ the front of the rear fender.
