About Touma, IMO, that's not Law manipulation and conversion to existence just seems wrong, all that Touma did was destroy the cloud, CRC coming back to existence is a natural consequence of the cloud being no more, Touma himself didn't directly cause him to come back.
As for Aleister, please just stop using "same as in base", mainly because he's clearly 5B physically in the Aleiszon form so that's wrong anyway, he should be plain 5B and that's it, not like there's even such a thing as "normal spells" by Toaru standards and much less when it comes to Aleister.
As for his abilities, there's no reason for him to lose his type 6 immortality, the fact he could possess Coronzon's body after his death is by itself proof he kept this ability regardless of the Crowley Hazards being annihilated.
