No good art for it yet, but I've been thinking about a turbo-prop version of the Ju88 and/or '388. Part of the problem is the lack of a credible engine. I want to avoid the HeS011-based versions, as the engine would never really pan out in RL. A quick fix whiff could be a second turbine stage on the 003 or 004 jets to drive a prop. Or, for more whiffery, a development out of the 006, using the idea of the variable turbine stator, use it for a second turbine stage instead to take advantage of the potential variable power output. The 006 would be an interesting engine in general. Smaller in diameter and lighter than the 004 but with nearly the same power, at least potentially.
