Complete latticeability in vector-valued sequence spaces

First we adjust a technique due to Jiménez-Rodríguez to prove the complete latticeability of the set of disjoint non-norm null weakly null sequences and of the set of disjoint non-norm null regular-polynomially null sequences in Banach lattices. Then we apply the mother vector technique to prove the complete latticeability of $λ_π(E) \setminus λ_s(E)$, which implies the complete latticeability of $(\ell_p\widehat{\otimes}_{|π|}E)\setminus(\ell_p\widehat{\otimes}_πE)$, where $E$ is a Banach lattice and $1 < p < \infty$.
