Logically, if you look yes anyone can play ASR. In fact, you can choose any actor to play the role, but and this is a big but, would that actor be able to leave a lasting impression on the minds of the viewers that they are unable to accept anyone else in that role? A character becomes memorable on screen only if it has been interpreted and acted well.
Barun Sobti was able to reach into the very essence of Arnav Singh Raizada and he portrayed it brilliantly. Audiences were able to see past the stern, iron clad exterior and see the man behind the mask. ASR is a real man, a man who has deep flaws, a man who loves his family that he will give up his own life for them, a man who is unapologetic about loving his family, a man who accepts when realises his flaw makes amends to it. Even when the character of ASR was mistreating the character of Khushi, people saw past his anger and connected to the vulnerability that propelled ASR to be the way he is to Khushi.
Yes, there are a lot of actors out there in the world and maybe there can be others who can play the character but...
There is only one God Father and that is Marlon Brando;
There is only one Al Capone and that is Al Pacino;
There is only one Don and that is Amitabh Bachan;
There is only one Gabbar Singh and that is Amjad Khan;
There is only one Dream girl and that is Hema Malini;
There is only one Bobby and that is Dimple Kapadia;
There is only one Mogambo and that is Amrish Puri;
There is only one Bhuvan and that is Aamir Khan;
There is only one Ishwar 'Langda' Thyagi and that is Saif Ali Khan;
The list goes on and on...
And finally, there is only one Arnav Singh Raizada and that is Barun Sobti.
