An extensive generalization of the ordinary and quasi-eikonal methods ispresented for the $pp$ and $\bar pp$ elastic scattering amplitudes, which takesinto account in a phenomenological way all intermediate multiparticle statesinvolving the crossing even and crossing odd combinations of Reggeons. Theformalism in this version involves a maximum of three parameters correspondingto the intermediate states which are possible in this configuration. Theunitarity restriction is investigated and particular cases are discussed. Aninteresting result that emerges concerns the Odderon trajectory intercept: wefind that unitarity dictates that this quantity {\it must} be below or equalunity unless a very peculiar equality exists between the coupling of theparticles to the Pomeron and the Odderon.
