Moving an apple tree

I've just seen the sad news that this forum is closing One more post in before then and a big thanks to the kind folks who have helped me with my handful of questions on here, Loire all stars.

so...I'm finally tackling the end of a long garden that's been neglected, and the previous owners put in an apple tree way too close to wall (about 80cm away). It's also next to hedging next door so the tree has been leaning into the setting sun, however is about 9 foot long.

I'm trying to work out what to do with it; I like the idea of cutting it down for an espalier option (would be my first time) along the wall, although I'm concerned that it's leaning so badly that I essentially would have to it down to the base anyway. So I've also considered just digging it up to straighten it, but I don't know what my chances or successfully moving this would be, or if I should split the difference and dig it up, straighten it and keep it in the current space and then espalier it.

FWIW they are jonah gold apples, and last year it produced approx 80 apples and they were pretty good.

Suggestions appreciated!
