No no no no - Please no!!! I was given a Czar Plum and told that it was a small tree - It turned into a 'monster' and the plums were pretty woolly. We did not even attempt to move it to this house, and it was only 3yrs old!! I have popped in a Mirabelle which has stayed shrubby as promised. You could try a greengage although I've found them slow growers. Dwarf Stock Trees are normally a safe bet, but I hesitate a little having seen your photo. Very tight space.
