That is not true.
No you cant just swap coure shocks into charade the hub are different so its better if you dont like the ride of your car to get original charade shocks.
Because charade hubs parts are also not available like the caliper kit and all so my mechanic sugested we should change the shocks + hubs with coure.
In Sultan ka Kho u can find them at Qaiser Autos make sure when u buy the shocks as the fitter to remove the spring and than check the shock properly it should be very hard to move it up down and the rod should be neat and clean no scratch marks.
Regarding the gas shocks i spoke to my mechanic he told me this that gas will make ur ride very rough so its better stick to the stock ones.
BTW see if you can return these if you dont like these ok.
Its better if you cant return these than go for change if needed after EID.
