I suspect that even the early overweight pre production aircraft will be well out of what Jet2 are willing/able to pay.
Low cost long haul is still in its infancy a few New York flights at peak travel periods isn't long haul
Jet2 would IMHO be taking a huge repetitional risk in trying to do serious long haul with 27 year old 757's a great aircraft for sure, but high risk at that age
