Arjun-Abhay inspired by Big B-Kaka for Chakravyuh?

Would Chakravyuh turn out to be one film that may pay an ultimate homage to Rajesh Khanna? If the core plotline of this Prakash Jha film is any indication, it seems to be inspired by Hrishikesh Mukherjee's Namak Haraam.
"Namak Haraam was about a rich industrialist (Amitabh Bachchan) who asked his friend (Rajesh Khanna) to infiltrate his factory's trade union and work for him by breaking the union. Similarly, Chakravyuh too is about a cop (Arjun Rampal) who takes help of his best friend (Abhay Deol) to enter a Maoist organization and pass on information to him", informs a source. 

In Namak Haraam, Rajesh Khanna's character was shown to go through a change in heart and he ended up being on union's side, hence taking on Amitabh Bachchan. Similarly, Chakravyuh too has Abhay ending up being influenced by Om Puri and Manoj Bajpayee (who lead the Maoist organization), hence resulting in a clash between him and Arjun. 

While the treatment is of course expected to be different due to a change in setting, one can be rest assured that with an intense actor like Abhay stepping into Kaka's shoes and Arjun Rampal going a la Big B, it would be an unlikely, though a well timed homage to the man who is no more.
