Summary of German attack on France with pertinent points
The game already models those advantages. Radio is a flat 10% bonus right there, before we even start talking about doctrines. You get some good doctrines in the mix, and your CA bonus shoots up, you can concentrate more brigades per division (which equals more concentration of force), and you can get combat events that let you steamroll the enemy without difficulty. And Germany can research it all thanks to high leadership.

Exactly, Alex put it best, so I'll just add a litttle to it.
The Germans may have made it look effortless but it wasn't. It took years of preparations and grand strategic thinking. Guderian didn't just come up with the radios in each tank on a whim, he had to convince the high command 5 years earlier. Combined arms was again something he worked on prior to the war, as were mobile infantry units, which he thought were neccessary for his style of warfare. It wasn't about tanks, the French had better ones. Having the better technology wouldn't have helped the French, because the German victory came from the pure genius of people like Heinz Guderian and the fact that that he was allowed to let his brilliance shine. And you can't trully put a value on that, but reducing the German delay by an extra 24 hours would probably help.
I'm not even sure it would help with the problems you see Germany having. If, as you claim in an earlier post, it's an AI problem, not your personal problem, then reducing AD by 24 hours just for Germany won't help them win. The AI already gets bogged down in stiff fighting in France. Reducing attack delay won't help the AI avoid manpower loss. It might even speed up manpower loss thanks to a faster operational tempo (And really, that's all AD represents is operation tempo, as modified by battlefield conditions (blitz combat events)).
If, on the other hand, you think AD is affecting YOUR performance as Germany, then just go deeper into the proper doctrines. If 24 hours of AD makes such a big difference for your playstyle, then you gotta grab those techs ahead of schedule. It's not like Germany can't afford the leadership cost.
This does not even factor in the bonus to all combat units Germany gets from initiating the war in the first place. That initial buff from the Blitzkrieg decision is nice.
I'm actually not sure AI Germany has that big of a problem with AI France. Yeah, it's not as efficient as its historical counterparts, but Paradox has created an AI that tries to play to win within context of the rules. The historical French leadership (despite warnings from guys like de Gaulle) weren't playing to win in the context of the rules. So how can you expect the German AI to fare as well as historical Germany if France is going to play the game that well? After all, France is not tied down by its historically bad choices in doctrines, either. A human or AI can research good doctrines before the war and play catchup. Hell, France can even fire bad generals and put good ones in charge (France has them, they are just buried in the OOB.)
What you are asking for is a magical buff for Germany to overcome a perceived inadequacy in fighting the French when, in fact, it is the French who perform better than expected. You could instead just nerf France more than they already are (or even make France's AI stupid), but that would make the game way too easy in other ways and make it pointlessly difficult for those playing France. (If you've ever played France, you know it's the wimpiest major power in the game in terms of manpower, IC, and starting army right now.) While we will disagree, I think that as long as Germany beats France 90% of the time, I have no problem if half the time it takes 5 months or so to do it.
