I imagine if this was actually a thing this is how it would have went:
No input or holding HP netted one the current Seichuse godanzuki; perhaps with some lower damage. LP help would get Midan uki, low damage but perhaps able to continue the combo afterwards akin to U2. mP would net one Judanzuki, with higher damage than Godanzuki, but with limited oki afterwards. Huskiesnzuki might’ve netted one OMGWHATTHWFUCK damage but required one to have Tanden Renki active.
