To give it that interwar French look (which is generally to say, as ugly as sin) if you could find some angular or disproportionately bulbous turrets for the nose and dorsal positions, they would fit perfectly. They'd probably need to be modified, have the framing sanded off and repolished, but something bulbous like a B-10 turret or the like would suit the bill.
Only one rifle caliber MG, of course.
