Replace the Junkers Jumo 004 Turbojets on those Me 262 or Arado Ar 234 Blitz whit the American-build General Electric J31-GE-5 turbojets or the British equals. those US or Brittish-build engine have about the same performance compare to the german jetengine exept it have mutc better lifespan.

That´s not easily possible. The GE J31 is too large in front area and diameter due to the radial layout. It would require larger nacelles and hence a taller landing gear to clear the nacelles from ground, thus increasing the weight. The 7t+ -262 would now have an even higher wingload and drag for less top speed, and lower crit Mach figure, while other performances are identic.
That´s no good trade, esspeccially if You factor that other german jet engines, such as the BMW-003 had acceptable service times (200 hours), comparable poweroutput but are less heavy and less large. With BMW-003 You can reduce the take off weight of the Me-262 to 6t. max (altough the original -262 wouldnt have got swept back wings with -003), with the HeS30 the max. take off weight would be around 5.6t. max with much lower wingload, better endurance, lower drag and better top speed, respectely.
