It is an interesting thought.
The straight wings would likely give the Meteor an advantage at lower levels, but at combat altitudes it's hard to know.
The Meteor's centrifugal-flow engines were also hardier than the axial-flow units in the German aircraft, which had very short service lives indeed. They had the same problems as the Tiger tanks, wondeful machine, impressive engineering, but a damn pain to keep maintained compared to their counterparts under field conditions. (Though if we are talking about a 'what-if' scenario I guess you could surmise that the Germans had the alloys necessary to make the engines reliable.)
The 262 was fitted with the R4M to use against bombers, and they were effective, though I don't think they'd be much use in a dogfight. The Mk108 cannons in the nose also had a low muzzle velocity and a very steep trajectory. I imagine trying to shoot down a fighter doing ~450mph would be incredibly difficult.
