Back budding on a big old Prunus gardendori

I got the chance to dig this oldish Prunus (probable avium) last week, but there was no way around trunk chopping it.

As you can hopefully see from the photos, the tree is old enough to have rough bark on almost everything I managed to keep (save a tiny piece of a branch off the minor trunk). That watering can is 10L, for scale.
I only have experience with younger Prunus avium, who don’t even miss a beat if you trunk chop, providing they’re ramped up/newly dug (IME). Do any of you have any experience with something like this? Do you think there’s a chance I get new branches? How lone do I wait before I mark this down as a loss? Any input appreciated.
