my two sense coming up

no no no no no, just no, those surfaces just aren't big enough, you need nice big 3D surfaces to move the slipstream from the prop. It will be an absolute pig.
P51 is for shooting down focke wulfs and ME109 when did you ever see a P51 prop hanging over a runway, it just ain't real, guns are pointing the wrong way anyway.

just my 2c.
