As I posted a considerable time ago on this (and other) threads, various people have been saying 'It must be possible', or 'A fix is about to be released by XYZ company, watch this space !', and then it all goes quiet again.
Here in the UK, where diesels have been a lot more popular for a long time, nobody has managed to delete the EGR and/or DPF as yet, and that's with 5 years of work going into it.
Quite simply, the systems are hard-coded into the car electronics. As the EGR (for example) opens and closes, the car expects to see other readings, taken from other sensors, change (for example inlet air temp). If those readings don't change as expected, then the car throws a fault code.

While I don't disagree that it is difficult to do; the system in these cars is hardly any more advanced than the Bosch system in modern Volkswagen diesels...
I think the issue is actually more one of demand rather than technology...
