I think it will work . I thought a bradford pear was a real pear . It's just a cultivar grafted on rootstock , like most fruit trees .This one has been selected for being fruitless is all.... .The problem with them dropping branches ,I think is because pears want to grow tall and thin ,and in pear orchards they tie ropes on the branches and pull them over and down ,in order to encourage the tree to bush out .Bradford pears are Topped ,and so they sprout many weak side branches.
But I may be wrong.
