Well no point making you recap everything again or wasting what you have. I’d suggest Just rework the upper parts and add a second set of the same motions but with the upper body different as an update to the pack. Don’t charge additionally for it though your packs are already pricey. Which is why its a bit of a miff to buy a pack and not use it at all for a reason like this. Though in itself for a unique look it could be cool for a single character in a game or animation. But in terms of reuse it doesn’t blend well… I’d prefer just a pose like Sub Zero fight stance, (minus the thumb up). The open lead hand is kind of a “nice” touch to separate it from a standard mma or boxing stance… too i suppose. Just some thoughts.
