To make it more balanced I also think that you should:
-adjust the launch angle of jab so it goes a bit more forward
-greatly reduce the hitstun for u-air (please)
-make the b-air slightly smaller
-decrease the knockback of forward air to make it easier to combo with it
-slightly lower the run speed
-make side-b be faster with less aerial drift after the attack

Also not really a balance suggestion but have you considered making a Brawl Mode?

i havent mostly because i dont really have enough experience with brawl (i havent played it in years) so no i most likey l wont.

nerf nair if you didn't already, last time I played him in balanced his nair still covered his entire hurtbox
