Hello again,
I don't know how distressed the tree is and if there's any damage or rottening in the roots so I wouldn't take a risk and cut back the tree. Even if I had I would do it early in the spring, when the tree is most vigorous. I would suggest that you just wait until the end of February and then apply prunning if there are any dead or deteriorated branches.
If you have any further questions please let me know.
