Could we get a new Sami Zayn upon his return?

Recently WWE superstars Sami Zayn took to Twitter to update people on his road to recovery. For those who do not know Sami tore both of his rotator cuffs during the match with Bobby Lashley at money in the bank earlier in the year. Here is said to be out of action for the rest of 2018 and into a good chunk of 2019. With not much info coming out since he went on the shelf, we only have this to go on.

Could this mean we get a new sami zayn upon his return? New aggression? more charismatic? A whol new persona? There's still so many questions but this definitely gets us excited.
