Definitely! Getting LHB would be the best option.
I was only pointing out that IR didn't even follow up with the easy solution. ICF coaches are already anti-telescopic like LHB coache and As long as the coach doesn't flip over or rotate about, they are reasonably safe. With just a change in the coupling style, majority of the rolling stock can be made safer. When a small investment can make such a big change, it is not being researched actively. That is a bit disappointing.
