Can I edit a file to complete the story, but still have the legendaries available?

Let me explain. I want to start a White/Black save file, then use PKHex to change the Event Flags in such a way that the game reacts as if you already went through the story, got every badge, beat the E4, etc., but the Legendaries are still available.

I don't even know if this is possible. I thought about just going and checking all the badges, event flags, etc., but don't know exactly what to check/uncheck for the game to react as if I just recently beat the E4 and have all legendaries available.

Is this possible?

1. Get a complete save file

2. Respawn legendaries by toggling their event flag

3. ???

4. Profit!

OK. Thanks.

So I just uncheck the "Cobalion disappeared" box and the same for the others?
