^^^^ Try with Mosquito nose too. 
Mossie nose is too wide & just replicates the 2-seat idea.
Meteor nose works well - 4 x 20mm guns & single seat -- basically why the Beaufighter was designed.
Cutting the top-deck of the Beaufort brings it back to the side profile of a Blenheim but with a wider fuselage, hence the Beaufighter's new fuselage -- but your profile does look nicer.
Would suggest the RAF mate the Meteor nose to recycled Blenheims as an easy medium fighter.
