There's no one really like Akihiko in this game. At best, I suppose there's Slayer. Dandy Step might have some similarities, but the moves don't really function the same way. And I guess you'll have a character that has difficulties getting in again lol.
But since Slayer has an unconventional dash and is more footsie/link based, he might be a hit or miss for you.
If you're looking for a character that gets to press buttons and stays in easily once you're in, there are other options.
I'm coming from the same place. I loved Akihiko in P4A and I am leaning towards Slayer because he looks cool and seems like he's a boxer, kind of?
Are the links super difficult? That has always been my problem with Dudley in SF4.
