first is the Divine 128 strikes move... since it hits for less damage per strike than 64, and only attacks one more time, could it become able to freeze the opponent for a short period of time? sort of like the sharingan freeze, but a much shorter range? second move is makyou hyoushou, and this would make it much stronger... after a certain ammount of uses, could makyou upgrade so it takes more chakra per jump, and possibly initial chakra investment, but actually leave illusions/clones behind in the mirrors, so its harder to tell where the user is and when they hit certain mirrors? easiest way i can think of to do that would be when they hit a mirror, leave a clone that mimics direction their facing, as well as looks... plus it would give the opponents a minute before it sets up completely... be able to knock the user senseless if they can XD second move is kinda a huge powerup for makyou, but since haku clan doesnt have virtually any jutsu... and their strongest/only attack jutsu is Sensatsu, which is very very weak compared to pretty much anything else (clan jutsu wise), this upgrade becomes just slightly more reasonable :O though i'd still understand if you see it as too rigged to implement XD
Actually, from what i notice 64 and 128 do about the same damage per strike, i think equal to my tai. That still means theyre both horribly weak, though, since i can use jyuken to do as much as 2x my tai damage with a regular attack.
