They might not die immediately but it’s a perfect canvas for any fungal 
nasties flying about. Have them out and replant. No point faffing around with 
grafting when this much damage has been done surely?

I wouldn't give up on these trees because of the "ring-barking".

 

Having tried to do exactly the same with other sycamore - legally, with the 
owner's permission but on behalf of a neighbour - it took three visits over 
three years with increasingly deeper cuts with a chainsaw before my sycamore 
started to show any signs of damage in terms of foliage..and the process was 
only stopped after the new owner decided to remove the trees completely.
Trees were well and truly still alive at the time of felling. Experiment 
finished but I learnt a lesson that these damn trees just don't read the text 
books, nor listen to social media. I'm guessing cuts need to go as far as the 
nonconducting heartwood of a diffuse porous tree to kill it.

 

In commercial terms where ring barking was undertaken to kill trees en masse 
it was often assisted with a good dose of 2,4D or equivalent.
