Problem ICF coach se nahi hai. Problem uska coupling se hai. If the rake just had CBC couplings, then the coaches would not have rolled off, preventing a lot of casualties. Even if IR does not give LHB coaches to all trains, they should at least convert the existing ICF rakes to CBC rakes. That will guarantee a similar performance to LHB coaches in most common derailments.
Talgo would probably be even safer. Talgo coaches are made of extremely durable Aluminum alloys which are lighter than the steel used in our LHB coaches, but are equally strong. And their bogie-less arrangement means that coaches will not roll about randomly during derailments. In fact, their wheel arrangement...

makes sure that the train does not move laterally. Also don't forget that the coaches are designed for high speeds. They will be designed to withstand high speed derailments and impacts by default. Don't let their small size fool you!!

It was not a failure exactly. The experiment was shelved as there was a call for converting all trains to LHB. It was one of several experiments tried out when IR failed to come up with a good self-generating system for LHB coaches. Several experiments were tried out to incorporate the safety features from LHB coaches in to normal coaches like CBC couplings and H-LHB coaches. And like a lot of other experiments, this was abandoned in between to focus on another half-cooked project.
CBC couplings will always give heavy jerks compared to screw coupling, no matter the type of coach. But it is not a unsolvable problem. LHB's give lesser jerks as the coupling has been suitably...

modified. And similarly H-LHB coaches ( which use ICF bogies) were also modified to reduce CBC jerks. All the MG rolling stock from ICF also have CBC couplings ( it's just a different kind of CBC coupling). It is just a matter of pursuing it till the end.
