I like to get my knight behind c4 and I don't mind exchanging that pawn, I just don't like it to get stuck behind my knight, therefore I often play the English opening.

Is there an established opening where both knights get behind c4 and f4 pawns? Even if that means exchanging those pawns with the d or e pawns? I mean, is there an opening where it goes like:

`c4 Nc6, "or something", f4` and then later on Nf3 followed by Nc3

if so, then how well does that opening score?
