Pear tree questions

Didn’t see a similar post when searching, link if I missed it.
This pictured pear tree is at my Mother in Law’s house, and she doesn’t want it. She has been pruning it recklessly for years to the point where there is such thick growth in the center, no airflow or light is possible. Wondering if any of y’all fruit tree experts would be able to answer the following:
Can this be pruned correctly at this point or is the damage done?
Can this be transplanted at this point or is it too mature?
Anything else you see that could help a pear lover out?

You can always thing out some branches.  As far a transplanting it you would need a pretty huge rootball and if it did survive it would spent years regrowing it root system. I’m guessing the trunk is somewhere around 6-8” at least so I am not 100% if this applies to fruit trees I do know for shade trees figure 1 year per inch of trunk recovery. I’m sure it is similar for fruit trees.

Id thin it out so it can breath and plant a new one if you want one. Rob the old tree of fruit while the new one grows.

Oops. Just saw she doesn’t want it. I revise to add step one. Convince her to keep it and tell her you will prune it and pick the fruit so it doesn’t fall and rot on the ground.

I have seen rally large trees transplanted by people who know what they are doing so it might be worth looking into an arborist who has the right equipment to dig up and transplant the tree.

That is a really nice-looking tree.  The shape appears to be right.

I agree with this:

Joe said "Convince her to keep it and tell her you will prune it and pick the fruit so it doesn’t fall and rot on the ground.

And tell her you will bake her a pear pie and make lots of preserves to share with her.

Oh boy have I tried. She is the most confusing person in regards to her "landscaping". I have tried and tried to tell her that putting the blueberry bushes in the back under the shade of other trees will ensure they fruit and grow as little as possible, but "that's where I like them" is all I get.
The pear tree was meant to be small and now it is "too much to prune each year" I offered to prune it last year to help its growth and ensure that it will actually put off decent fruit, but when I came to do it, she already had. It is so thick with growth inside that you can barely put your arm into it. The only fruit that sets on it are on the very outer edges and they end up riddled with issues from what I assume is poor airflow.
I was thinking it may be too big to transplant by myself and likely too expensive to have someone else do it.
