mermoz92, thanks, you answered several of my questions, if only implicitly.

So, you want a flight like that...fine, let's triple the price of your ticket.
As an engineer, I don't think it would add that much weight, hence not that much to the price of your ticket.
Look at the seat rails, which IIRC already are supposed to take 15G?
Replace the underfloor stiffeners in the aisle(s) with trolley rails integrated in the structure. Would need new trolley wheels, probably in titanium to take the stress.
I doubt it'll happen, not because it can't be done, but the logistics of the changeover would be horrendous.
And CAT and flying trolleys and injured CC and SLF are (thank goodness) so rare that they still make the 'media' and even PPRuNE, which in itself signifies it's not exactly a common occurrence.... so nothing will be done about it.
Yes I'm a cynic, but also realistic....
