Thank you for responding. Yes, what you speak of sounds like a superset of what I was considering. Also, I found that this is not a new idea at all ("implicit capture") but rather has been implemented in other codes (MCNP, Fluka).
Though what I had in mind was something simpler, in that what I had in mind was low-ish energy (<400keV) X-rays going through shielding. These do not generate so many daughter particles, so one could model it pretty effectively by just modifying the weight.
Since I want to do a computation in the short term I will try using the importance sampling technique, but I will look forward the the availability of implicit capture or something similar in GEANT4.
