It's not possible or else Sairaorg would have increased his demonic powers. Issei might have gained more control of his demonic powers which allowed him to teleport through a magic circle which any devil can do no matter how low their demonic powers are. Issei has the Boosted Gear and when he Boosts, he increases his demonic powers. And wearing the Scalemail enhances and increases everything for Issei. Strength, speed, demonic powers, etc. But his base demonic powers are still that of a low-class devil's. Why do you think he has to Boost every time he wants to use Dress Break or Bilingual or use Dragon Shot when he's just in his regular Boosted Gear state?
