Question about Big Bang and HP

Question. My White Knight had low HP because I messed up the SP in the first job. I eventually fixed it, but the only way I could get my HP back up was to use AP on it. If I use the free AP scrolls to reset my HP and put that all into Strength, will my HP reset if/when the Big Bang comes to GMS, since the HP gaining and MP gaining formulas changed?

Thanks in advance!
