No you do not get stat boosts from your abilities. You can say you get a boost, and it is generally agreed, you get a bonus, but no specific stat raises. The stats are there for people to have an equal advantage, over the next person. I may implement a rule, so that those with stat boosting abilities, can do so, but we cannot do that at this time. So no, you cannot have those extra bonuses. If you had a higher than normal spiritual power, then you might be able to have the kenpachi skin(that's how he did it, his insane spirit pressure, blocked attacks. But yours is only a 20. It would only be as strong as a normal captain.
