Retargeting FPS Light Pack to Ironbelly Studios Skeleton

Hi Guys

Not sure if someone has these packs and has tried to do something similar, but I have the following Packs:

  1. FPS Light Pack - FPS Light Pack in Props - UE Marketplace
  2. Animated Arbalest Crossbow - Animated Arbalest Crossbow in Weapons - UE Marketplace

I am trying to retarget the animations from the Light Pack to the Ironbelly skeleton. I was able to retarget the arm animations properly and they work fine, however, I am not sure how to get the light items (flare/torch etc) to be held in the hands as the sockets are different.

This post is a little specific and just wondering if anyone has used these packs and been able to retarget them properly and if so, how did they go about it.
