There is another important parameter which I forgot to analyze.I am assuming China doesnt have 229 and 220 class PW engines with similar specs.
Weight of engine. F-100 are heavier engines means there will be noticeable shift in center of mass of aircraft.
This shift may effect aircraft overall aerodynamic performance unless it is brought back to original position by manipulating various equipment and fuel cells locations, TO and landing distance and speed will also be effected.
Chinese engines of this class do not produce this much thrust.
