If you don't have any OHxF series rootstocks, you might try direct grafting to a piece of pear root.  Although I wonder if there is another rejection mode at work because I have a European pear on a seedling pear and it still only grows about two or three inches a year.

I don't know a lot about pear compatibility and I don't make many pear trees.

I have a list of pears which are compatible with Old Home and those that are
compatible with Quince and when I doubt, I usually put the unknown pear on Quince
with an Old Home interstem.

Three years ago, I received a request to propagate an unknown European pear (tree
about 100 years old and wood was weak, but acceptable) and I just can't make it
grow on either Quince-OH or Quince alone. It hasn't died, but the growth is a
measly three inches/year.

Last year I got a request to propagate another unknown pear (60 year old tree in
good health) and it seems to be failing on both Q-OH and on Quince alone. It also
didn't take on Asian Pear (20th Century).

Any suggestions?
