No, writing using the wrong storyform won't warp your ideas in the wrong direction. Weird, huh?
Okay, yes, you can wrestle your ideas into submission to a storyform if you want. But generally if you listen to your gut and go with "but this is what I want to write" then you will not do this, and you will end up with a rough draft that's in okay shape to build up from.
But, I think I have diagnosed your issue here:
No! There are no ways to do this. But it doesn't matter. Ready for the magic spell? You have to cast this on wherever implement it is that you work with: your computer, your desk, your special pen
First draft, I know you're gonna suck
I'm not gonna take it personally
You're actually being very nice
Because one day
I'm gonna throw you away
You're just a step toward the second draft
I'm serious about this. Your first draft is you, just about to get in the shower, paint in your hair, armpits smelling... and your date shows up early. Be nice to it. It is being way more vulnerable than you would ever want to be in public, yet here it is, baring itself to you knowing that you are going to turn around and critique it and come on the boards and tell people that it's got no structure or meaning. Would you do that for another person? I sure as hell wouldn't. So be nice to it, say thank you every day, and then when you type the last paragraph of the last chapter, turn around and take the knife to it.
