I believe the speed is too ambitious.
Tony Butler's books have some information the DH 102 but it carried about 4000lbs (at best, four 1,000lb short or two 2,000lb bombs inside) and was estimated to do 404-417 at 25,000ft using Sabre IVs.
Perhaps something could have been done with the Centaurus using Tempest or Fury type cowls?
Something like a big Mosquito. Start with Sabres until the desired engine - the 2-stage Griffon - is available. Wing profile stolen from Tempest. Fowler flaps.
Have De Havilland make it.
Out of wood or aluminium?
Can we get an early Canberra?Impressed by the performance of the Mosquito prototype and early production models, the RAF looks for the next generation high speed bomber aircraft.

The Halford H-1 Goblin did not fail in the XP-80 as such... the XP-80's inlet ducting failed under the suction.Not likely.
UK jet engines of the period were 2-2,500lbf thrust, compared to 6,000-8,000lbf thrust for Canberras.
Derwent V is available near or after the end of the war, had 3,500lbf thrust.
The de Havilland H-1 Goblin I had up to 2,700lbf in production models, but these were thin on the ground before WW1. The failure of the H-1 in the XP-80 prototype delayed de Havilland's Vampire because the engine that was to be used in the prototype was shipped to Lockheed instead.
The Lockheed P-80 ended up with the J-33 of around 4,000lbf thrust. Four service test YP-80s made it to Italy by 1945.
Don't think the J-33 would have been available in quantity soon enough for an early Canberra to make it into the war.
In an extra what if scenario, if Whittle had been supported by the Air Ministry earlier and/or Griffiths had been sent to an aero engine manufacturer, rather than Metropolitan Vickers, more suitable jet engines may have been available for an early Canberra.

Last Goblin Mk was nearer 3500 lbf
Probably '47 - 50. Was a very well engineered reliable engine. First ran within a year of Halford seeing a Whittle compressor wheel and being let into the secret.And when was that?
