Sorry, but it quite definitely was the aerofoil section that limited the top speed of the Me 262, and 0.92M seems highly optimistic, probably due to a pressure error effect. The engine nacelles being below the wing, they would not have interfered with the fuselage flow in the same was as they did on the P-38, for example. Swept wings would indeed have helped, but the resulting aircraft would not have been a 262.

As for your contention that all high speed twin jets had the engines in the fuselage, what about the multiple variants of the Yak 25 family? The Bristol 188 testbed and the SR71? Or, in more modern times, the Tomcat and the Flanker? Certainly there were many other projects, even if they didn't reach fruition, that retained podded engines.
