Not a huge expert, but from generations of farmers, so know a bit about hedges, (planting as well as uprooting
).
You've not got a lot of root there for some quite large bushes.
I would be very brave and cut the tops right back to about 18" from the soil level, then plant in really well prepared soil with some lovely compost/leafmould etc. Don't let them get waterlogged, but also don't forget to water them. If they survive (and they probably will) they'll shoot again from the bottom and you'll get a lovely thick hedge in a few years' time - if they don't, well they probably wouldn't have done anyway so what have you lost? 
Good luck
