Japanese maple-is it dead?
Your poor tree is really struggling.
We wouldn't recommend trying to move it. Even if it were to survive the odds of it ever thriving are quite low. It seems to be missing bark in several places and it's gracious form will not fill out given it's prior pruning and leaning difficulties.
We suggest starting over with a healthy, vigorous tree, well placed in the landscape in an area that gives it what that particular plants needs and wants, including the space to grow freely to it's mature size.
