The trees are unfortunately incompatible in the experiments i did using seedlings only. I tried osage orange on mulberry but not mulberry on osage orange that i recall. I keep thorough notes and may look back if time permits. @tonyOmahaz5 my experience is limited to the experiments i did at the time of our last experiment and the years prior to that, ive not done experiments since then. Do you have additional experience since then? After my experiments were complete i am satisfied. Not all seedlings are genetically the same and someone may find one compatable some day Like winter banana apples can be grafted to some pears or vice versa there is a species of mulberry or osage orange out there that is the bridge tree to connect the mulberry and osage orange. Finding that tree can only be done by trial an error many times. Ive done that work with pears but am not commited to do it with mulberries. Someone will continue the experiment we did. We built on the experiments @Lucky_P had done years prior. Hopefully someone finds that tree soon but noone has had a good enough reason yet. That has been nearly 5 years ago since we did that last experiment. Once you find the compatible tree you can use it as an interstem Interstem aka interstock Pear Grafting. Im convinced it exists its a matter of finding it. Things like bread fruit and other tropicals are relatives but are not cold hardy or i would be looking hard at other similar members of the family of trees.
