1.) The XB-15's profile if rotated nose up around 2-3 degrees does vaguely look like the Mosquito NF variants if you blend the nose turret with the nose: You'd have to thin the top fuselage a bit however.
2.) I've tried doing a scale-o-rama with the XB-15 and DH Mosquito but it's very difficult as the engines of the Mossie partially occlude the nose -- cutting out the engines and wings is easier said than done.
