Yes...as you go to pot the scion cut off that bud at the top that has sprouted. Paint the wound with wax or a sealant so that no water can escape from the scion. Then with luck a dormant bud down the shoot may just break. Fingers crossed though.
What I'm hoping is that the scion will start to root before that bud breaks.
If the bud breaks first....then it may well die before the root takes over. That's why I hope that the lower buds are fully dormant still.
As to age.....a tree that size may well be 80 or more years old.
We've got Blenheims that age with the same hollow trunks...and still going.
