So, as the title states, I found out that you can load arrows against a blocking opponent and be completely safe afterwards.
You can do this by doing either B13 or 33 against a blocking opponent and immediately loading trait, which will result in you being anywhere from -4 to -6, which is completely unpunishable by flying uppercut (fastest reversal in the game) but you cannot backdash afterwards which lead me to believe that it is -4, -5 or -6 because backdashes are universally 3 frames.
Now the pushback from both is significant so most characters will not be able to pressure you, B1 is 16 frames and stand 3 is 15 frames so it's sort of hard to set this up in neutral, but it's guaranteed after an arrow reset, also, the same can be done for F2D13 (sort of), F2D13 arrow load is around -7 or 8 since it can be punished by flying uppercut, but 90% of the cast can't punish you (i think it's only 2 or 3 characters that can punish you) because of the pushback.
I also found a completely impractical piece of tech with this, you can do B13 or 33 canceled into arrow dash cancel forward and still be able to block flying uppercut, but this is mostly useless anyway.
