There were huge difficulties to get working burners in the early days. Putting the heaters in has a significant effect all the way forward through the engine.

Whilst I agree that a homemade afterburner would be sporting achievement, remember that a key feature of afterburner is that it "should" have minimal effect on the core engine.
