I'm in the same boat as you, absolutely adore The One and think it smells amazing. But the projection and longevity is terrible.
I've heard of some companies that make fragrances that are identical to other fragrances on the market, but in EDP version. So you'll get a fragrance for example like The One, in Eau de Parfum. The prices are $35 for 50ml. So it's worth it.
I've smelt a Tobacco Vanille copy, and I swear to you, it smells exactly the same and it also last 10+ hours.
