I recal a long time ago Pyro mentioned it,( I beleave he did).
I think it would be very cool, the Storch, and the FW 189 are two of my favorate planes.
I think they would be fairely surviable, their very slow spead a nd superlative handeling would make them extreamly hard to hit.
The FW 189 could also cary a usefull load, and I beleave later models had 20mm cannons.
