I was wondering if I were to transplant this to a pot and begin to bonsai the tree, cleaning the roots and putting it in better soil, could I successfully turn the tree into a nice bonsai or would the tree always be effected by leaf curl?

It would be a shame to lose it as I do see a lot of potential in the tree as a bonsai in the years to come. If there is hope, when would be the best time to dig it up?

Any thoughts would be greatly appreciated.
