I have had shothole on prunus cistena crimson dwarf shrubs
i found Bordeaux Mixture at leaf fall, bud burst and mid spring to be very effective. A winter wash or a couple of neem oil sprays too.
my plants are dwarf vwrieties but yours are prob far too big to spray Abby.
There is no cure and shot hole will gradually weaken any plants. I would try to grow these trees as well as possible...good feeding and mulching.
if you do decide to replace your trees avoid similarly susceptible ones.
