Do you actually want to repair and recover this one? ...or are you more inclined to keep her as is for a memorial piece? If you want to recover this one, it could be done any of several ways. I'd think perhaps a long (3 -4 inch) scarf joint for each limb to a new handle riser. ...perhaps with Fiddler49 style wraps or ties to hold it all in place. It could be done, ...she could shoot again.
...or you could just invest the same energy into the next one.
