There is a very good reason that all the methods in the forwarder class of NFD use const for Interests/Data packets. Because the forwarder is not supposed to change the packets at that point of the execution. I would suggest if you want to change Interests, create an application that could do that.

Make sure that all the node's neighbors run a producer app that has registered a specific prefix. The node should run a consumer app to send Interests for the registered prefix. Please take a look at the existing consumer and producer app implementation in ndnSIM.
Hope that this helps,
