You're right, they're not interchangeable in that the flap tracks on a 152 are shorter and only allow 30 degrees of travel. Everything else should 'fit'.
However, I wouldn't count on the wings being airworthy. They're more of a complete 'kit' to allow one to modify existing standard-range wings to long-range wings. In addition to the tanks themselves you'd also need the different ribs and tank covers.
