Jeez, is the Mossie not good enough for you guys???
The Mossie we have is not really a night fighter. For the best night fighter of the war we'd need the Mosquito NF.Mk 30. Did about 430mph at ~27,000ft. On the deck it would be a bit slower than the Mosquito VI we have already.
And yes, hunting B-29s in a Mosquito Mk 30 does sound good to me.
