About the only thing ya can do with it now besides a shorter string, is narrow up the tips as much as you are comfortable with, and trap the outer 3 rd of the limb to the belly aggressively. That could get those outer limbs bending a bit more. Doing that is going to drop your draw weight , but it will seriously cut the hand shock down. I’ll bet that one has some kick to it as-is.
Next one go with a longer riser, and use a power lam to extend the fades out past the riser fades another 3-4” . That will force the limbs to bend further out on the limbs. Kirk
