The POD might've looked like this - during the BoB, LW realizes that Ju-87 is vulnerable without fighter escort. Thus a decision is made to produce bombers that might not rely so much on fighter protection, while carrying a worthwhile gun- & bomb-load per horsepower installed and crew used, along with meaningful protection. How might've the proposals looked like (apart from the OTL proposal of Ju 187)? A reasonably short development time is required, with Jumo 211 engines preferred but not a strict requirement.
