Are there any hacks to a Flash Gordon-similar setting? Pulpy raygun action. Preferably set in the Solar system: like Rocket Age and Tales of the Solar Patrol.

It seems that there should be something done already?

I am aware of Barbarians of the Void, but want a more specific 30ies serial era setting.

Have you heard of Red Venus for Everywhen?  It's not exactly what you're looking for as it's set after WWII but you might look at it.  It's pulpy solar system based scifi.
