Grafting onto less useful trees

I was surprised to find out people have been grafting pomegranates onto crepe myrtle. Who knew!

I've heard of pears on hawthorn and quince; pecan on hickory. Of course, ornamental pears are an obvious choice to graft onto.
This year, I am trying hybrid persimmons on American persimmon again.

Overall, I prefer trees that are not grafted, but want to experiment.

Does anyone have any other less known combos?

I feel it is great that you want to learn how to propagate fruit trees by grafting.

What kind of trees do you have in your yard that you can experiment on?
