If your willing to dig into the code, anything is possible :) More specifically though, the instruction count event as well as many others are based off the event queue infrastructure inside of m5 (src/sim/eventq.hh).
Adding your own callback could be done by just scheduling an event on the main event queue. I guess the most straightforward example of this is the "TickEvent" found in the O3 or InOrder CPU models. They derive from the "Event" base class and when their event is ready the queue calls the "process()" function. If you want to add your own code, you could define your own event and then write your own process function. There's examples of this throughout the src code but following how the "TickEvent" works is probably the best way to get started with that (src/cpu/inorder/cpu.hh,cc is an example).
