I rebent 1 million Mafac levers because they needed such a long reach,much longer than most Peugeot,Gitane or Mercier buyers could muster. We would just use a schwinn seat post and bend them back closer to the bar sometimes for very small hands we would add more hook.
They are quite malable and should straighten out quite easily.
