Whoah...that seems like you will be rushed. I'd break it up into two trips. Fly to Berlin, then go between Berlin/London by land. You'll see more and experience more of Europe...
Why not go to Egypt for a week or more next year?
also, i researched flights from london to egypt. they are neither cheap nor short! i would be worried about losing some days due to jet lag and travel time. definitely split it into two trips or try to get 3 weeks doing berlin and london (with some stuff inbetween) and then on to egypt.
